Burgers and a Dip!

Following my amazing night of diving with friends Enjoying the view before gearing up to explore the wonders beneath! it was time to catch up with the divers of Ocean Pro for a fun day of diving and good food.  After a quick clean of the cabin and loading all the gear back into the vehicles we headed over to the main parking lot to find and hold spots for the rest of the group who would soon be arriving.  With the sun coming up and a warm day ahead we started by laying out any of our gear that had not totally dried over night and started putting our kits together in preparation for the day.

It seemed only minutes before the parking lot was full and the air was filled with the talking and planning of the days activities.  Amongst the group joining the activities were my close friends and instructors Virpi Kangas and Ward Conley, their plan for the day was taking them out in Wards small boat so they could dive the Nakaya.  Other groups were heading out to swim the fire-hose, while others were setting out to explore the Leaning Tower of Porteau or the Sailboat Hull and others still were off to explore the Granthall.

My dive partner for dive 1 of the day was an experienced diver joining the Ocean Pro BBQ for the first time.  Equipped with his twin tanks and local knowledge it looked like it was going to be another relaxing day of diving... boy was I in for a surprise...lol.  Apparently swimming as fast as possible was an on-going trend for this weekend. Not long after entering the water my dive buddy started his quest for an Olympic medal in swim sprints...lol.  It was all I could do for the most part to keep up and finally signal my buddy to slow down, by this time unfortunately I had burned much of my air so it was time to make my turn and head back.  My dive buddy on the other hand, swimming with twins, had lots of air and was less than agreeable to returning quite yet.  After a quick conversation through hand signals it was decided to make another pass around the Granthall, this time very slowly and breathing under control, then after our pass, we followed the chain up to 15 feet where we did our safety stop sharing the air in his twins and then made our way the last 15 feet to the surface.  On the surface the tides had changed from the night before and now the surface current was now heading away from shore, making the surface swim a lot more challenging.  After a bit of a fight against the current to gain a few feet it became apparent that it wa going to be easier to work together.  So taking turns doing the tired diver tow with us both kicking the whole time we were able to make faster progress against the current and reach shore in time to see the burgers coming off the grill.

Stripping down my gear and switching out my tank only took a couple minutes then it was time to open up my dry suit and enjoy the fresh air drifting into my suit and cooling my body down.  Soon most of the rest of the divers who had not already returned made their way over to the big Ocean Pro Divers tent to find their fill of food and stories about the first dive of the day.

After a quick meal, and some good conversation it was time to catch up with my buddy for dive 2, who happened to be the same buddy from the night before.  Dive planning for our last dive of the weekend was pretty simple, both of us a little tired from the night before and from our surface swims from dive 1 on the day, agreed we would dive similar to dive 2 from the previous night.  Surface swim out a short distance and then descend and let the water moves us around while we explored the open ocean floor.  Finding our neutral buoyancy and just floating in the water with soft gentle kicks to change direction or increase rate and it wasn't long before the current had moved us back out to the Granthall, a couple circles and then over to the fire-hose which we started to follow back towards the first marker.  Then it happened, they tell you it happens but until it does you don't know what it's going to be like.  I stopped, spotting a particularity interesting plant that appeared to be swimming, and decided to snap a few pictures. 



1, 2, 3 frames later and I look to my buddy.... he's gone... nowhere to be seen.  Random clouds of silt can be seen in a few directions, unfortunately due to the large number of divers in the water clouds of silt could be evidence of any diver.  So, checking my watch and marking the time, then resuming my previous pattern sweeping side to side it was time to look for my buddy.  15 seconds, nothing, 30 seconds, nothing, 45 seconds, nothing, a minute.... nothing!  Now it was time to hope my buddy was ok and would stick to our plan, if separated, look for a minute, then head to the surface.  So... off to the surface I went spinning 360 degrees during my ascent looking to see if my buddy could be spotted.  Upon breaching the surface, I again started my 360 degree surface search looking for any sign of my buddy.  Only problem, lots of divers on the surface.... unfortunately... my buddy was not one of them...  Could it be that my buddy hadn't noticed I wasn't with him?  Is he ok? Where is he?  Seconds seemed like minutes and two minutes seemed like twenty.  Still spinning on the surface looking and then there, about 200 feet in toward shore, was my buddy, waving and signalling "OK".  Taking a navigational heading to where he was and indicating to stay in place, I descended to avoid the strong surface current and swam the distance following tight to my navigational heading and close to the bottom surfacing just beyond arms distance from my buddy.  Staying close and both stilled stunned at how quick we got separated we moved to the stairs and up out of the water to warm up, stow our gear and head home safe, sound and reminded of the importance of strong buddy contact.

Enjoying the view before gearing up to explore the wonders beneath!

Saturday afternoon while the Vancouver Canucks were preparing to dish out their punishment on the Boston Bruins, I was meeting up with a few friends at our cabin up at Porteau Cove.  The plan for the evening would see us completing 2 dives before calling it a night, catching some sleep and then joining Ocean Pro Divers in the morning for their monthly BBQ and dive day!!

By the time I had arrived at the cabin, my buddy for the night had just arrived and the Canucks were going into OT tied 2 - 2.  After grabbing my over-night gear and throwing it on the couch and flipping on the TV, we were just in time to see the puck drop and Alex Burrows suck Thomas out of the net, out skate Chara, and wrap around the net depositing the puck in the back of the net taking game 2 sending the Boston "ruins" back home to lick their wounds.



Shortly after the game, the third member of our group arrived and started preparing his dinner while I walked down towards the shore to look and see what the tides were looking like for the evening and was met with this wonderful view:


The water was so calm, only a few clouds in the air, conditions we dream about!

After my walk, the last of our team had arrived for the night and we loaded our gear and headed for the shore.  Taking our time to discuss the plans for the night and review any concerns we geared up and decended the stairs to start our first dive of the evening.

Surface swimming out to the first marker, the plan was to descend to the bottom, group up and move out along the fire hose exploring the darkened ocean floor.  Upon reaching the bottom and forming up in our buddy teams we headed out across the bottom.  Unfortunately the other group of divers turned out to be determined to move as quick as possible and since my buddy and I were looking to actually explore the under-sea world instead of watch it blast by while setting a record for how fast we could swim.  It did not take long for the other group to pull well ahead of us as we watched their lights dim into the distance.  Signalling to my buddy we slowed down to a complete stop, checked air, confirmed depth and started a slow patrol of the bottom moving in the general direction of the second marker.  After slowly exploring and capturing a few photos we started our slow return back towards the stairs watching as the fish dashed in and out of our beams of light.  Before we knew it, nearly 40 minutes had passed and we were watching as the bottom angled up and our depth drew down.  By 45 minutes we were back at the base of the stairs, regs out, fins off and then the short walk back to the vehicles to switch tanks and head back.

As it turned out, the first group had returned before us and had already stripped down their gear and packed it away.  One of the divers had decided to wear a wet-suit for the night, so after dive one he was uncomfortably cold and his buddy had decided one dive was enough for the night.  My partner and I, however, couldn't wait to get back in the water so while our friends headed back to the cabin we headed back out into the water, this time with a slightly different plan.

With me taking the lead we surface swam out just far enough to have about 10 feet of water below us before we descended.  Upon reaching bottom, we checked for neutral buoyancy, confirmed air and direction and then completely relaxed, slowly kicked and let the water move us slowly across the bottom while watching the world move around us.  As we approached half air we made a slow turn and moved back towards the stairs enjoying the underwater world and the wonderful life that it revealed to us along with some interesting looking animals that I had never seen before and will have to see if I can find someone to identify.



















After finding and photographing our little buddy here we made our way to the stairs and up to the vehicles to strip down our gear and head for the cabin.  Back at the cabin we spread out the gear that would be needed for the following morning to allow it to dry a bit before being needed again and headed inside to join the rest of our party. 

As it turned out it wasn't much of a party... inside the cabin our other two divers had already found their sleeping bags and were working on catching their zzz's.  Quickly grabbing a snack and something warm to drink I headed to bed to snore away my night and dream of what the next day might bring.

Row, Row, Row Your Boat Gently Into The Rolling Waves.... Merrily Merrily Off To See The Circus...

As crazy as this sounds this is exactly what I was up to on Sunday.  The day started with all sorts of confusion (which should have been a sign), Ward was still sick and as such would be unable to dive.  He was still coming to the site as the instructor and to make sure the day went well but since he wasn't going to be in the water we were being joined by Chloe Boone as the Dive Master for the day and another friend of the shop who would be assisting in the water.  The boats were at the shop, unfortunately  we couldn't find pumps... Finally we got a hold of two of the divers who were already on their way to the site and found out they had a manual pump from the shop and also had an electric pump for air mattresses.  So it was just a matter of throwing all the gear in vehicles, mounting up and heading out to the site.

Once on site it was evident it was going to be an interesting day,  as we pulled up we could see the white caps on the waves rolling into shore and feel the wind and see it bending the branches.  Now if you've ever been kayaking or in an inflatable boat in waves you know that going up and over and crashing into the waves is not the easiest thing when attempting to move a fair distance and secure to a buoy.

As mentioned fortunately one of the divers had his electric pump along which aided greatly in the inflation of the boats and then the manual pump was used to top up the boats.  A tank attached to an adapter was used to inflate the back-rests and with a little "chain gang" process all of the boats were completed and ready for use.  The next step was getting kits built, it was at this time that it turned out one of the divers had forgotten to check his gear and was missing his fins... normally an issue but ta da... I had a rental set and my force fins which meant I could loan out my rentals and we were back on track.  Now, with all the kits built and accessories gathered up it was time for the briefing.  Standing at the top of the stairs and viewing the water we went through our plan and groups for the first dive.  The plan, originally, was that Chloe as lead would be with me and my typical team and the other DM joining us for the day would dive with the father / son team. The whole group of us would stay together as a soft team but each of us had our hard team partner that we were not to get separated from.   With the plan in place as far as which buoy we were tying to, and how best to stow, release and don your gear, we headed off to grab our boats and start moving gear down to the beach.

Now once your gear is strapped in and you have waded out far enough and then jumped onto your boat and grabbed your oar and started paddling you can easily see who has done this before and who was not so experienced...lol.  I spent so much time trying to get the boat through the waves and pointed in the right direction I could feel myself getting tired long before reaching the buoy.  Meanwhile one of my typical dive team and my direct partner for this dive was able to pull far ahead of the group and easily reach the buoy before the balance of the group.  Now to add humor to the day my partner, the first one to the buoy, the one who was supposed to get us tied to the buoy, was also the diver on my Search and Recovery dives who had some issues with tying the knots, so as you can imagine this just added to the confusion and entertainment.

What we looked like from shore I can only imagine... six boats and seven divers all trying to stay clustered together around a buoy while scrambling to tie the boats together and tie one end onto the buoy.... Needless to say, despite the added excitement, we ended up tied together and secured to the buoy.  With that step completed it was time to get our gear on... the idea for this is to unstrap your kit and (after ensuring air is in your BCD) slide it into the water and tie it, clip it, hold it, close to your boat while, with your fins on, you slip into the water and put your kit on.  Now for a few people on Sunday this turned into quite the spectacle and was even worrisome for me, but after a deep breath and with flashbacks to my days with Virpi in my open water class (Seals to Emergencies) "I went one step at a time, pushed my tank down, sat on it, spun it around behind me, put my arms in the straps and slid off letting the tank and BCD rise to my back... bing, bang, boom... straps done up and I was done..."  Smiling probably almost as much as I did the first time I put my BCD back on in the water, I  established buoyancy, secured my accessories and headed over to where Chloe was getting the group all together.  With my team in place, and group two assembled (wow, starts to sound like a military operation...lol) we signal to descend and meet at the bottom.  After a beautiful slow and relaxing descent with eyes on my partner we settle in just above the bottom and wait.... and wait.... and wait... after a few minutes we conclude that the rest of our group is not joining us and must have had an issue so we start our very slow and relaxed ascent... back up to the surface.   On the surface is where all of the real excitement was happening.  Apparently with the switch from Neoprene suits to the Bare Nexgen suits and from steel tanks to aluminum tanks, two of the divers had dropped too much weight and were now not heavy enough to get down.  So, with the aid of our guest DM who stripped his weights and split them up amongst the under-weighted divers so that they were be heavy enough.  Of course without his weight his dives were done for the day so he became the surface manager, and the two divers that were supposed to be with him, now more heavily weighted, got to join up with the rest of us as one big group.  Now to try it again...  Descent attempt number two... after a bit of a struggle with fins, which were switched out with our guest DM's, as he wouldn't be needing them, we managed to get down a fair way towards the bottom, but unfortunately due to a couple more issues one of our previously under weighted divers returned to the surface and needed to call off that dive.  So down a diver and a DM it was off for the third attempt of dive number one...lol.  (Welcome to the circus) Now that we were all (with the exception of the two on the surface) making our descent to the bottom together the dive had officially begun.  Descending down to 80 feet and swimming just a short distance off the bottom we started looking for the sunken Sailboat the Nakaya, it took only a few minutes to find it and start our swim around it.  We had discussed some of the dangers of the Nakaya while on the surface and decided to make a hard rule about no one closer than 10 feet to the boat, it's rickety condition did not bode well for any kind of in depth exploration nor the safety of any diver who tried.  I did manage to get off a few pictures but the water was pretty murky and I'm still not very good with the lighting underwater.   But before I could get off too many shots we got to the next phase of "fun,"as I rounded the corner of the sailboat, my main focus on capturing a picture while my partner was just ahead and to the right of me, when something caught my eye.  One of our divers was almost right upside down facing towards the bottom with Chloe holding him down and trying to reach something in her pocket.  Quickly dropping my camera to my side I cut down beside her along with one of our other divers and at her indication, forced open her pocket (by the way neoprene sucks under water, it condenses with the pressure and makes neoprene pockets next to impossible to open.)  With my hand wedged into Chloe's pocket I managed to pull lose the weight she had stowed in there and pass it to her to be secured to the diver in issue.  Unfortunately with all the activity I had burned through more air than I planned to and needed to signal to ascend.  As I signaled it became apparent that the additional weight added was still not enough and the diver with Chloe close behind slowing his ascent went straight to the surface.  With only the three of us still down at depth (my usual team that I have been diving with for a while) we each signaled and very slowly and collectively made our way to our three minute safety stop then on to the surface to end dive number one.  Once on the surface confirmation was received from Chloe that everyone was fine just a quicker trip to the surface than they would have wanted to.  Now with the dive complete, it was time to strip off our kits, ensuring air still in the BCD (I can only imagine the results of forgetting to do that and dropping your tank and fully weighted BCD into the water...lol. Guess I'd be making good use of my search and recovery skills learned in Hide and Seek! and Arrrr' We be searching for yer burried treasure! then...lol).  With kits off and floating in the water close to your boat, it's again time to practice skills from Open Water to use fin kits to assist with getting back on board your boat.  Then haul up your kit, secure it in place and head for shore.


Now before anyone gets the wrong idea, yes this day could have gone better, but it also could have gone WAY worse... I learned a lot on these dives and felt so much more confident as a diver after the day.  You see unlike many of the dives before where much of it could be done without thinking, today really made me pay attention to not only myself, and my buddy, but also learn to pay close attention to what other divers are doing around me as I experienced in dive 2.

Now with Ward sick and unable to dive, one DM without weight and fins (loaned out to one of the under-weighted divers) and Chloe having just made a quicker than planned ascent, we were without staff divers looking at one more dive on the day.  This is when the true skills of the OPD staff shone through and why I will always be proud to say I am an Ocean Pro Diver (maybe even one day honored enough to join the elite divers pictured on their website).  While enjoying our surface interval Ward posed the question and challenge in saying: "Ok, you're all Open Water certified so you don't need in water supervision, you are here to learn and practice the use of the boats and the staff will be present for that but for the actual dive you don't need us with you so tell me what your plan is."  and at that he just looked at us.  Though it took only a second, I saw divers grow in confidence ten fold.  Suddenly we were responsible for the dive, we had signed up for Boat Diving lessons and were getting everything we paid for.  We were learning how to load and secure gear and dive off boats, that's Boat Diving, but we were also learning so much more.  We were divers, we didn't need our hands held, we knew how to dive, it was the boat part they were there to supervise.  So after that quick second (and some prompting from Ward) it was decided to do the fire hose, a simple dive, fairly close in and not very deep.  This would allow us a short row, conserved energy and due to the delays on the first dive this would help us recover a little time so that we could be out of the water and on our way back before dark.  The second thing that happened that absolutely made my weekend, was when Chloe pulled me aside and asked if I would partner up with the diver who had experienced some challenges on his first dive and perhaps as a result could be feeling a little more stressed than normal.  Well... this shot my confidence (and my ego...lol) up about 14 notches... a Dive Master... and Ocean Pro Dive Master... was asking me, to keep an eye on one of her students.  WHAT A DAY!!!

Well... I have discovered the fastest way to take a guy (me) who over-thinks everything and make him a better diver... give him someone else to worry about...lol.  On dive two we rowed out the short distance to the first buoy, now practiced with our tying techniques we were tied up and ready to don gear in just a few minutes.  With gear in the water and all of us functioning as a team we all got our kits on, gathered around the buoy, partnered up, signaled and descended.  Now I don't know whether it was because I was so intent on not letting anything happen to my team or what it was, but I seemed to have no issues with anything.  My descent was perfect, just before bottom I added a short puff of air to my suit, and slowed to an almost dead stop.  My buddy... not so lucky... he decided to take a close (VERY CLOSE) look at the ocean floor...lol, no problems with being under-weighted this time...lol.  Readjusting his buoyancy and finding his "hover" we were ready to go.  With the other two divers in the lead, my partner just in front and to the right of me and me bringing up the rear, we headed out along the fire hose at a very relaxed pace enjoying the scenery.  With our plan in place to turn back at 2000 psi, my buddy signaled me, and with a quick signal to the divers up front, we circled and headed back to the ascent line, back to the boats, kits off, resecured and paddle back to shore. to stow the gear and head back to the shop.

Now some people will read this and see the issues on the day, or comment on the potential dangers of diving.  But those who see it from my stand point, those that understand and accept that no course just like no dive, is ever perfect.  It's not about perfection... at least not for me.  If you learn Navigation in 30 feet of water with 40+ feet of clear visibility, did you really learn to navigate or did you practice opening your eyes and swimming...lol.  For those of my long time readers you will have noticed that nothing ever goes exactly as planned and that is when the "real" learning happens.  We finished the night with Ward having us go around thr room to list off what we learned in the day, not surprisingly, no one mentioned learning to dive from a boat.... everyone learned something else whether it was to always check your weighting, or always check your gear before leaving for the site or in my case, ways to be better prepared to tie up the boats... everyone learned something... and that is what made it such a success!

It's Dark... Very, Very Dark....

So last night marked the first two of our five Adventure dives, needless to say I was a wee bit excited.  The shop had given me new gear to try, this time using a neoprene dry suit.  So after calculating the additional weight required to account for the new buoyancy of the suit, I was all good to go.  So with Virpi as our guide we geared up and descended into the depths.  Our first of two adventure dives on the night was our Wreck dive,  after a surface swim (I hate surface swims.. lol) to the Grant Hall marker, we grouped, signaled and descended to set foot, for the first time, on the deck of a boat that has been serving as a natural reef for years.  Once grouped at the bottom we made a slow search around the wreck both down where it was buried in the silt and along it's upper surfaces.  With our lights on and a careful scan of the underbelly of the ship we were able to discover an octopus den, not sure if our friend was at home or not, but you could tell he had been eating well, by all the crab shells outside of his house.  A beautiful kite fish caught our attention as it skirted along the bottom of the ship but staying just long enough for us all to have a good look.  Along the upper surfaces of the Grant Hall we were able to meet up with a Decorator Crab, no, not Martha Stewart, this is an actual crustacean who uses bits of seaweed, sponges and debris and sticks it to itself as a disguise, I didn't see him until Virpi pointed him out and disturbed the water nearby so that he moved a bit.  Then out of the corner of my eye I caught what surely have been a shark or a barracuda or some other man-eating creature of the deep.  It ducked down inside a crevice between a holding tank and the bulkhead, (ok, obviously not a shark...) so me being inquisitive (and a little dumb) I moved in on the crevice to take a closer look and with the help of my dive light, found myself face to face with one of the largest Ling Cod I have ever seen.  He must have been about 12 feet long and at least a thousand pounds... ok, maybe 4 feet long, but the menacing look he gave me was really scary.. lol.  After a quick once more over the surface of the boat we found ourselves back at the chain and ready for our ascent to the surface... and another surface swim in and back out for our next dive, our last dive of the night, our Night Dive!

So after a quick break, a Nutrigrain bar and a tank change, no that's not code for bathroom break, although it would work, this was an actually tank change, we headed back down the stairs of Porteau.  After some trouble with my fins, which should have been a sign that this was not going to be my night, we made our surface swim out the the marker buoy, fortunately not as far this time as the Grant Hall, and prepared for our decent.  I'll stop here so you can get a idea of what this looks like, it's after 8:00pm (closer to 9:00), it's dark, darker than dark.  Here in the city, night is spoiled by light pollution, street lights, neighbors, headlights, etc.  up at Porteau we have a couple parking lot lights and the lights in the distance on the opposite shore... it's DARK!  Add to that the fact that we are now going to drop down 30+ feet below the surface loosing color, light and visibility more and more the deeper we go... it's REALLY REALLY DARK!

Here is where life gets interesting or mildly more dramatic, unfortunately I was already having issues with my buoyancy by this point, neoprene is more buoyant so it takes more weight and a slightly different approach to obtain and maintain neutral buoyancy.  Little did I know I was already coming down with a cold and my lungs were already working harder than they should, add the fact that my jaw (a long standing medical issue I've been dealing with for years) decided to act up after nearly 9 months of no issues.  So lets condense, we have me 30+ feet under water, pitch black except for my (and my groups) dive lights, body already tired and sore, lungs already working over-time, and a dry suit that wants to make an ascent to the surface with or without me...lol.  So we are going to practice our Navigation swim, again not a skill I am fond of but one that is essential.  My job is to swim in the direction Virpi points, keep my needle in the marks, and my partner counts kick cycles, hit 15 cycles, turn around and swim back keeping the needle in the reverse position and after 15 kick cycles we should be back where we started.  Sounds simple, and I am sure for those with a decent sense of direction or even me under normal circumstances it would have been ok.  Now remember, I'm already having issues, so here is roughly what happened, my partner and I started to swim, I can't see bottom, all I can see is my compass and all I can feel is my partners hand on my arm.  I am struggling for some reason to keep the needle in the marks and my partner is pulling at my arm, not knowing what he was trying to tell me I turn to see him giving me the thumbs up, which in diving means ascend, so I turn to ascend and grab my low pressure inflator for my BCD to prepare for my ascent, look at my partner and break the surface... completely disoriented, I thought we were still right along the bottom, apparently the pulling at my arm was my partner realizing I was ascending the whole time and he was trying to signal that I was going up.  After getting my bearings and swimming back to the marker buoy with my partner we started our re-decent and that is when the "fun" started.  The hood i was wearing was too big for me so when I looked down on my decent and exhaled, the air caught in my hood, sliding my hood back and pulled my regulator out of my mouth. Unfortunately I was inhaling at the time and took water down my throat.  It's funny though, looking back, how fast your training, if you are trained by good instructors, kicks in automatically.  Upon hitting the surface and knowing buoyancy was my first and only concern, I reached for my BCD low pressure inflator, unfortunately my gauges were still over my shoulder from the navigation swim so I couldn't find the inflator, so I did the next best thing, I inflated my drysuit, giving me enough buoyancy to take a breathe or two, take my gauges back off my shoulder grab the low pressure inflator for my BCD and add air to my BCD.  Now that I was floating safely, it was time to kick back to the marker so that I was centralized for when my group surfaced, engage my lights in the possibility that in the dark my group may see the light above and realize I was still on the surface.  Sure enough, after only a minute (seems longer when you're waiting) my group surfaced, checked on me, we got regrouped and descended for a tour of the dark bottom and a surface swim back to the vehicles and on our way back to the shop to switch out tanks then home to rest.  After-all, we'll be back in the water today.

The "future" and the past!

Today marked my first session of ocean dives in my Open Water certification.  We had our gear from Thursday night and after lugging all this wet gear into my house including gear bag with BCD, Regs, mask, snorkle, fins, boots, gloves and hood, my undergarments, a bag with my "dry" suit, my weight belt  and weight bag containing ankle weights, bullet weights, and my integrated weights and, last but not least 3 full air tanks. I got to carry it all back outside this morning at 7:00 so that I could load up in my dive buddy's vehicle and drive to the dive site.  I barely slept last night, excitement, nerves, all of the above... whatever it was... not a great sleep... thank goodness for Monster energy drinks...lol.  Morning was great, got lost a couple times going to the site, but we found it (good thing we left early and allowed a lot of time).  Unloaded everything, started putting together our kits and got everything lined up for ocean dive number one.  But before we can dive.. we must... da da da...

TEST!!
So, 50 questions, multiple choice, covering all 5 chapters, minimum 75% to pass... that's like, like, like.... oh man, my brain is so full of diving I can't remember my math.... what in the world is 75% of 50... this should be so easty... it's... it's... oh yeah right 37.5, thank you to all of you screaming that out for me... lol.  So, if I can manage 38 right.. I'm golden.  I'm doing OK out of the gates, "What happens to air in a balloon filled at the surface as you descend to 30 feet?" "B", "What happens when you ascend with a glass full of air?" "A",  "What are the most important features of an exposure suit?" "D, all of the above"... lol.  Then we get to the eRDPml (remember this from Tuesday "  ") Now for those of you who remember high school math where you had the word problems like "A train traveling from Chicago headed to Seattle detouring through Salt Lake City traveling at 75 miles an hour except in the mountains or during lunch on Tuesdays, leaves on Friday at 2:03, with 271 passengers 5 crew and a full luggage car.  What did they serve for lunch?" lol.. will understand what it feels like to use one of these dive calculators under pressure on a test that decides if you are diving, or just watching!.  Needless to say, I passed.. I managed a 48/50, 96% missing 2 of the dumbest questions that I should be shot for missing, on one I ended up selecting the box for the obviously wrong answer that they throw in there as a gimme...

Well, we all passed, now into the water for dive one, on dive one we will have a tour of Porteau Cove and some of the spectacular life and items under the surface, dive two is skill tests and a tour and dive three is a few more skill tests before our final tour of Porteau Cove and the swim in.

Dive one, was interesting, we make a buddy descent to approximately 20 feet, group up and follow Dennis for our initial tour of the bottom.  Now to try to achieve and maintain neutral buoyancy, not as easy as it sounds, but once this is accomplished and you take your first few kicks of open ocean diving, you have experienced a small slice of heaven!  At this point the group is more or less relaxed, no more kicking so hard we stir up sediment, less crashes into the bottom and off for our first tour of our section of the cove.  It's amazing what you can see down there, crab everywhere, fields of jellyfish, starfish running (albeit not very fast) across the bottom and when you finally get your bearings and your focus, you start noticing the little things like the sole and ling cod and the occasional green ling.  What an amazing world!



Dives two and 3 were skills, like body breathing, mask and regulator recovery, introduction to navigation and buddy navigation and other basic skills followed another tour with Dennis in the lead and Virpi bringing up the straglers.  These dives were the best, by this point most of us had sorted out buoyancy issues, and had calmed down allowing us to just float through the water and REALLY experience the life down there you don't see anywhere else like over 100 species including octopus, and plumose anemones and some items from our past that you would never imagine seeing like the Granthall (a steal hulled tug boat), the Centennial III (a steal dredger) and a 15 m ferrocement sailboat hull.

Overall, this was the final thing needed to firm up my decision to keep diving as often as possible, because again, in the words of Nathan Hale Bridger - "For beneath the surface ... Lies the Future."

Dry Suit - "It's a relative term!"

Last night brought the last and final classroom and pool sessions for my Open Water course, we were again happy to have Mathew Mendes join us in class and in the pool and the always wonderful Virpi Kangas was able to walk everyone through their questions and put everyone's minds at ease over the upcoming impending 50 question final exam!  It was a good class, again most people had their homework done and it was great to have a few minutes to discuss gear with Matt and Shannon. They were able to educate me on the downsides of buying used equipment especially regulators, especially given the cost of service and the warranty on new ones.  Case in point, (actual example) I was looking at a used Apeks XTX 200, only $400!  New, this reg is $800, that's half off!!  What Shannon was nice enough to point out though, is (1) this is your most important piece of equipment, without it, you don't breathe, (2) a used one will need to be serviced, add $150, plus any parts count on at least $100 (if not more),  plus any additional parts down the road.  A new XTX 200 comes with a lifetime parts warranty and won't need servicing for a year (all regs should get serviced every year).  Overall, used is $650+, and any parts until the end of time... a new one is $800 parts included... for $150 (or less) in difference, I'm going new.  Shannon and Matt were also great enough to walk me through how to check tanks (as this is an item Shannon says can be a great deal used), they showed me where to look for the inspection labels, hydro stickers and engraved codes required on tanks in Canada.  All things that if you didn't know about could result in spending a ton of money.... twice!  Once to buy the "Great Deal", and once to pay full price for one you can actually use.   The conversation then turned to Dry Suits (which I was learning how to dive last night) and what to look for and the different levels and costs and accessories... etc.  Bottom line, if you want to do this right... it's not cheap!

As mentioned, class was great, we reviewed our Review Questions, and took our quiz... 10/10.. yeah me!  and then watched our Dry Suit video, and then got into the discussion (this was one of our review questions) on next steps beyond Open Water certification.  These steps include, Adventure Diver, this includes a taste of a couple of specialties (typically Deep Diver and/or Wreck Diver), then Advanced Diver, this includes LOTS of specialties to chose from and you get to try out 4 or 5. Then there is the big daddy of them all, the one I am looking at, the Master Scuba Diver Challenge! In this program you get all 12 offered specialties over the course of the year, your Advanced Diver and your Rescue Diver certifications.  This is the highest level of recreational diving and the door way to Dive Master and beyond if one is interested.  You end up saving almost half the cost over what you would pay if you paid for each specialty separately.  This is an amazing deal!

Last night finished at the pool as we learned and practiced our "dry" suit training.  After practicing our Controlled Emergency Swimming Ascent, righting yourself from an upside down (feet first) ascent, buddy breathing, mask recoveries (yes, again...) and practicing our Neutral Buoyancy we exited to clean up and found out that Dry is a relative term, I WAS SOAKED!!  Apparently doing aquatic acrobatics is not conducive to keeping all your seals closed...  I have been moderately assured that I shouldn't leak in the cold ocean... at least, not as much... weee!  Well, here's looking forward to an early Saturday morning, and my first of 5 Open Water ocean dives.

eRDPml... what? "All engines... full stop!", and the thing everyone likes to hear.

So last night marked the wonderful return to class, 2 chapters to review, my eRPDml to learn how to use (don't worry I had no idea what it was either... lol), 2 quizzes to take and all that before getting into the water to try out all the new skills. Soo much work.... so little time!  Of course we got it all done and under Virpi's amazing instruction, I even feel confident that I know what I am doing.

I  have, however, come to the conclusion that they have this course organized so that all the easy brain (my strong suit) and scary physical stuff comes at the beginning and the scary brain and not so difficult physical stuff comes last.  Here's why, in week one, classes 1 and 2, I managed to pull off 10/10 on both my quizzes, nailed all my Chapter Reviews and felt really good about the knowledge component (I even participated in class... imagine me talking.... never... lol). But when it came to the physical side, I was a lost cause... struggling and spitting and waiting for a priest to read me my last rights...lol.  (For more on that read through "Fitness... I don't need no stinkin' fitness" and  If it ain't broke don't fix it.... and from SORTED to super STARS.) So now we have had a week off, I even forced myself to go and redo the Fitness Test (yes.. without dying, although I think the life guards at Sungod were waiting for me to go under a few times,) and now we are back and we were to have the book finished and chapter 3 & 4 Chapter Reviews completed (some people didn't do their homework... tisk tisk..)  now it was time to review, discuss and then take our quizzes.  For the most part I did ok, most of my Chapter Review questions were done, couldn't finish the last of Review 4 on the eRDPml (I'll explain that in a second,) and scored a 9/10 on my quiz... I know there goes my 4.0 GPA, I placed the wrong number in the wrong order... I knew the right answer, just put it down wrong.... BAH.   So here is the scary brainy stuff I was referring to,  in chapter 1 we learned about buoyancy, atmospheres, and equipment, in chapter 2 we moved on to seeing and hearing underwater, more on equipment and working with your buddy.  Now we move on to chapters 3 and 4 where we learn about contaminated air, nitrogen narcosis, exhaustion, currents, tides, animal attacks and panicking divers.... at this point we have a classroom of panicking divers... ok, it might have just been me, but I just spent a week off, making sure I was working on my fitness which I thought was going to be the death of me, only to review all of the other ways I could die... yeah me!... lol.  So, we review all the questions in chapter 3, take our quiz (yes the one I only got 9/10 on) and proceed to chapter 4.  Chapter 4, as mentioned, includes more on all the ways to hurt yourself.. lol, including your pressure groups and understanding how these affect the amount of nitrogen in your body.  For this we refer to an RDP (recreational dive planner) or in our case, an eRDPml which, if I understand correctly, stands for Electronic Multi-Level Recreational Dive Planner (don't ask me why the ml comes last, it just does).  The eRDPml allows you to enter your dive information (is this your first dive of the day?, how deep are you going, how long will you be there, etc) and then will tell you what pressure group you are in, starting with A and ending in dead... I mean Z.  You can then use this letter to plan for additional dives for the day to ensure you do not exceed you maximum NDL (no decompression limit.)  You see how this starts to get scary... I'm having trouble even figuring out how to even use the eRDPml, never mind wrapping my head around the fact that this is not something you want to make mistakes with and add to that the fact that the system is built for the "average" person (whoever he or she is) and differs from person to person, often based on weight... yeah me!  Time to lose all the extra pounds I've been carrying around.   We review, and again thanks to Virpi's amazing abilities as a teacher, she breaks it down simple, and eventually gets me and my classmates through using the eRDPml and actually to the point where we were comfortable.... now off to the pool.

For anyone who has ever piloted a boat, then shut off the engine and tried to stop, you'll understand the humor behind hearing a captain say "Full Stop" or "All Engines, Full Stop" and know what it feels like to continue to drift without the ability to make a hard stop.  This is very similar in diving, or at least my diving, water is nothing like a road, if you get yourself moving too quickly (up or down), it becomes difficult to stop... at least under control.  So our goal for last night was to realize neutral buoyancy... for anyone who doesn't know what  neutral buoyancy is, picture it this way, a balloon in water will float, it is positively buoyant, a rock (or me at times.. lol) will sink, because we are negatively buoyant, but a fish that sits perfectly still in the water neither rising nor sinking, without swimming is neutrally buoyant.  It is a complex thing to think about sometimes, but the coolest thing to experience, much like being in outer space, you just sit there.  To achieve this you must learn breath control.  You ensure you are adequately weighted, with just enough air in your BCD and from there you just breathe... sounds simple... it's not.  Inhale too much, and off to the surface you go... exhale too much and prepare to meet the bottom.  This is where the "Full stop" concept comes in, if you are not careful, and inhale too much and don't exhale soon enough, you start to the surface and despite exhaling it is difficult to stop the motion, the same is true in reverse, if you exhale too much and don't inhale soon enough you start your decent and often it is too late to stop yourself from dropping to the bottom... this is a scary concept when you think about walls with 200 + foot drops below you and the problems with rising to the surface too fast .. you never want to lose control.. ever.  But once you have the concept and have practiced achieving this in a few different ways, there is little else cooler than sitting weightless in the water watching your classmates complete their skill tests as you sit, doing nothing, resting only on water, open space above and below you.  I was fortunate enough to have Matt Mendes, (again another in what seems to be a long line of amazing Dive Masters at Ocean Pro), in the water with us, signaling me to move up or down (ascend or descend) in the water while signaling for me to check and advise on air pressure, forcing me to be in constant control and alert of my gauges, instead of falling off to sleep due to the completely relaxing feeling of being weightless. Once you have this under control, and never one to want you to get too relaxed, PADI requires you learn how to breathe off a failed regulator... great... more things that can go wrong... is it too late to transfer to basket weaving as a hobby... lol.  To prepare for this and simulate a failed regulator, understanding of course that almost every time a regulator fails it fails in the open position venting air, you pull one side of the regulator out of your mouth and press the purge valve releasing tons of air and learn to "sip" air from your regulator without getting water in your mouth... it works!... I don't know how, nor do I need to, but it works and it wasn't hard.  We finish the pool time with practicing diver assistance, by pulling and pushing our partners back and forth across the pool, of course I had the wonderful assistance of Matt who, once again liking to keep you on your toes, took great delight in pulling me off course during my diver pull, forcing me to right myself and get back on course all without losing my partner who is "injured" in the water... oh the fun... lol.

So the evening ends, we clean up our gear, get it washed, packed and moved to the door, then off to change before loading the gear in the vehicles for our return to the shop.  It's on the way back from changing that it happens, words that are almost as great as the day my wife said "I do" and the times my parents said "we're proud of you", Matt looked at me and said, "You're doing really great out there" and just when I thought my day couldn't get better as I am sure I was floating all over again, Virpi echoed the comment in saying,"You're doing great out there, keep it up."

Life has it's defining moments, some are tragic events that we survive, some are memories of accomplishments past, and some are simply the kind words someone shares with you at a crossroad in life when you need to hear the thing everyone likes to hear... "Good Job."
