Missing Divers!

Missing Divers

Missing Divers

Even though I have only been a scuba diver for three years I have been a lover of the underwater world my whole life. I had always wanted to learn to dive, but with living a busy life it never seemed to fit in. There were other priorities that seemed to justifiably get in the way.  It was a tropical vacation to Mexico that rekindled the desire to learn to dive.  A gift of scuba lessons after returning is what finally got me my C-card.

Then like many scuba noobies I got my certification and promptly didn’t dive again for over another year.  Why? Why no diving? Honestly my dive buddy and I didn’t know where to dive.

We had a great open water dive in a stone quarry in Ohio. This location is just far enough away that it takes up most of a weekend to visit. Not someplace we could dive on a whim.  Other options were tropical vacations. They are awesome when you can scrape up the money to take them but they are not something that was going to happen very often either.  The last option (at least as I thought) was a weekly dive the local dive shop had. The problem with that was the weekly dives were done in the late afternoon the same day every week. The times were in conflict to those of us gainfully employed.

So over 16 months of no diving for me. No gear purchases, gear rentals or air refills. No stories I could share with the yet to be initiated about the undersea world. No planning for my next dive…

Take two happened earlier this year. My dive buddy and I decided that if we didn’t find a way to get in the water locally we wouldn’t get back into diving. To brush up our skills we signed up for an advanced open water certification. It was a good way to renew our skills and hopefully find a way to dive more than once every two years. We trekked back to the Midwest quarry and finished our series of dives to get our updated certification.

What next? We hunted for dives. There was a local eco dive a week later on a Saturday. It was something we could fit in. It was a beach dive at a youth camp. It was great! We did two tanks worth of diving and still had the rest of the day to spend with our families. Now this was the way it should be.

Still there was a problem.  No other dives… The local dive shop wasn’t doing regular local dives this year. Sure we could charter something a state or so away.  That put us back to taking up most of a weekend to go diving. There had to be a better way…. and there was. Dive local with a dive club!

Finding the local dive club was a challenge. Searching for dive clubs on the internet brought up 3 year old web sites with no updates. It makes you wonder if the club is active. Other clubs only had old posts on a message board with little information other than a contact email address. We finally found one that was meeting very close by. So close that their meetings were only 5 minutes from each of our homes. After an email we arrange to go to the next club meeting. This was the best thing we have done for our diving.

MUD Club Patch

MUD Club Patch

The club became an incredible resource. There are at least a dozen members that have been actively diving over 30 years each. Many of these club members dive at least 3 days a week.  Even when the weather turns rough it is rare for a week to go by without a club member doing a dive. They are eager to share their knowledge and fresh members just gave them a good excuse to dive all the old spots as if they were new again.   This was great! Since joining the club there hasn’t been a month that we haven’t dove.  All it takes is an open block of 4 hours and a phone call and we have a club dive going. The club also plans different events and at least once a month there is an official organized club dive. The best thing the club did for us is open our eyes to all the local diving possibilities. Every body of water in the area is now open to us thanks to the sage advice of our experienced club members.

So here is my next question. Why don’t local dive shops actively promote these ambassadors to diving? Are they afraid that I won’t buy their dive vacations if I dive local? Do they think these experts are going to bad mouth their business? Or is it that they believe with an independent source of diving knowledge we will buy all our gear online?  To me these are ring as conspiracy theories. I am willing to naively believe that they just don’t see the point in promoting the dive clubs.

I am convinced there is a vast underutilized pool of certified divers in the area that could be providing revenue to local dive shops and bring more divers into the sport. What percentage of divers here received their certification or worse yet just their book work here and only dive once every four years on a tropical vacation? I believe there has to be 9 missing divers for every 1 active local diver. I would love to see some real numbers.

As I help the dive club to promote I will be searching for these missing divers and trying to bring new participants into diving local.

Underwater GPS

Navimate™ - © 2009 Shb Instruments, Inc.

With the visibility of the water we frequently dive in it would be nice to have GPS underwater like most smart phones are capable of on dry land. If Shb Instrument’s Navimate™ sees the light of day underwater GPS could be a reality.

Navimate consists of a wrist mounted device that communicates to a surface based GPS gateway.  It lets you know what your longitude and latitude are and places it on a map that is displayed on the device. It will also display the locations of your dive buddies provide they are wearing one of the units and are within 100 yards of your location.

I am exciting about the possibilities. I see many useful scenarios for this device as well as making diving just a bit safer. I am hopeful that this device or others offering similar functionality will be available soon.  Shb is saying initial units will be available in the May/June 2010 timeframe.

Wrist units will retail for US$700 and the GPS gateway for US$300. I am guess as part of their initial marketing effort GPS gateways will be free to shops, clubs or other organizations that purchase a minimum number of the wrist units and will also be placing the gateways on selected dive boats at no cost. Instructor discounts for Navimate™ will also be available.

I have to credit Shb Instruments with publishing the price of the device. As with many items technology based I will hear about the product, get a fuzzy late quarter X release date with pricing TBD.  I am holding out hope that this is more than vaporware.

Our First Cold Water Wetsuit Dive of Fall 2009

Anyone who has watched me enter the water swimming would never believe I cold water scuba dive.  I am fine entering the water until my mid-section touches the water line and that is where it gets tough.  The chill jumps up my spine and tells my brain there is no way you want to get into that water. It must be a medical condition with a fancy name because I am too much of a manly man to be a cold water wimp.  Still I cold water dive either that or I would only dive in the hottest months.

Elinee Bay - Paw Paw Lake - Coloma, MI

Elinee Bay - Paw Paw Lake - Coloma, MI

Last Saturday I did my first cold weather dive of the fall 2009 season.  My quick verdict is that it wasn’t too bad. We couldn’t have asked for a better fall day. It was a sunny 51 degrees. The water temp was a balmy 49 degrees.  My diving buddies were Jim, Mac and Josh.

As promised I tried out most of the cold water tips and tricks.

  • I had prepared a warm thermos of coffee
  • I filled a cooler with sports water bottles containing hot water
  •  I had eaten a breakfast
  • I had my dry, warm wet suit and a box of rubber gloves
  • I had my 100% polyester long johns and socks on
The Pro

The Pro

I was ready. I made it to Jim’s house about 9:15 and we did the gear transfer to his truck and hit the road. We arrived at our destination about 30 minutes later. We were back to Paw Paw Lake in Coloma, Michigan at a spot off a fire lane called Elinee Bay.  Mac a.k.a. Donald M. had his gear nicely organized on a yellow tarp. You can tell he has done this a few times before. Jim, Josh and I start prepping our gear. Before too long we are ready to suit up for the dive.

Mac has gone the water jug route for “priming” his wetsuit. In the jug he has warmish (just above room temperature water) and he uses a cup to pour the water into his suit.  He says if his water is too warm he just cuts it back with lake water.  As I start to prep I can see my first rookie mistake of the day. My water is way too hot. I would say it was about 190 when I put it in the cooler. I honestly thought it would have cooled down more. It definitely can be too warm.   I filled my boots and gloves up completely with the warm water in hope that when I dump it out it wouldn’t be too hot. I left my socks on for this dive and was wearing black thermal long johns. I pulled my wetsuit up to my waste and primed about 10oz of hot water. Ouch!  Hot, hot!! And hot places you don’t want that hot.  I poured some of the hot water into my 3mm hood and then dumped the extra out. The water is still a little too warm but bearable.  I put on my boots and poured the water from my gloves down my wet suit sleeves.  I put another 6 oz down each sleeve and called it good. We finished gearing up and head into the water.

Normally I am so hot in a wet suit I can’t wait to cool down in the water. This time I am bracing myself for the expected cold. I could feel the first bit of the water seeping between my boots and the bottom of the legs of my wetsuit.  My feet were fine, but I could feel the chill on my calves where the primed warm water didn’t make it. I gave myself a few seconds and it started to warm up. Next stop the bottom of the zipper on my back. Oh yeah!!! Not enough priming!! I could feel the cold water seep in through the zipper. I didn’t try the rubber gloves trick on my hands this time but I can tell that it would have helped. Every time you touch something wet and then expose yourself to the air you hands really feel the cold. It would not take too much wind and a few degrees colder temperature and your hands would start to lose feeling.  We are ready to go below.

Jim, Josh and I have our dive planned out.  We start out decent. Every bit of exposed skin around your mask screams as it is submerged. Amazingly after the initial shock it is not that bad. Overall I don’t feel cold. The areas that were unprimed have warmed up and the primed areas I didn’t even notice the water. I am feeling comfortable. November is still fine for diving and makes for another month available on my dive calendar.  Visibility is about 3 feet before we start stirring up the silt. I quickly lose sight of Jim and Josh and decide to surface for a quick check. Josh has decided he is too cold. He has gotten a headache and decided to call off his dive. That is a great decision on his part. There are too many things to worry about when you dive and when you start off cold that can lead to worse things happening quickly. Jim and I float on the surface until we see Josh exit the water. We continue on with our dive plan.

We head to the bottom which is at about 25’ and work our way towards the shore line. Vis is less than 36 inches.  We start off in the sea weed and on our path head out of it. The bottom here is covered in about 8” of muck and silt. At one time this was a public dock so we are expecting to find some “junk” out here. As we did with our last ecology dive we are mucking on the bottom.  We set a steady pace that keeps us just ahead of the zero visibility we are kicking up.  A compass is invaluable in these conditions. Without it we would be doing circles. Even with it we do cross one of our own tracks. It looks like a giant mud colored worm as we pass through it. Visibility doesn’t extend past the inside of your dive mask. This is when it is important to not lose your dive buddy. Jim is on my left and we bump just to make sure we are close. He is ahead of me just a bit and I take a couple of extra kicks to line back up with him.  Somehow at this point I take a heal of a fin to my face and my regulator pops out of my mouth. Damn!

This is another instance where the dive training in open water really comes into play. Remain calm… breath out… sweep my arm out for my reg… grab it…. clear it and breath in wonderful air. Ahhhh! Just as it is supposed to be.  Jim and I regroup on the surface. As a diver you need to be prepared for this. You never know when it is going to happen and in the conditions we dive in it seems to happen more often than you think. I blame it a lot on the low vis we dive. Other factors such as having gear flopping around can also contribute to it too.

So far I had found nothing. Jim has found a beer can. If it is new and with a deposit we will have found $.10. Back down we go. We head along the shore heading out of the bay. By this point I was hoping to find just about anything. Last time I was here along the other shore we found tons of trash in a small area. My hand had touched buried sticks and other natural refuge but nothing man made. Ah a can! That got slipped into the bag. Jim and I tried clumsily trading hand signals. I saw he want to change course. He wanted me to lead, but I missed that part of the message. I slowed down to pace him and he slowed down some more since I slowed down.  Vis was getting really bad here. I found something with my right hand.  It was metal and has lots of edges to it. At first I thought it could be an i-beam or part of a dock. It moved fairly easily, but was still stuck in the muck. I tried to signal Jim and he was signaling me. I tried to move his hand so he touches the object and can give me a hand. At this point he is concerned I was in trouble or snagged. He started pulling on my arm for us to surface. This is just as the object started to pull free from the lake bed. Damn it was heavy. Jim’s pulling on me knocks out my reg again. Damn! lol That was twice in a dive. My right hand was occupied with the object so I can’t do my normal reg sweep. I grabbed my backup reg attached to my chest…. Clear it and breathed in wonderful air again.  I added some more air to my BC to compensate for my extra ballast.  On the surface we regroupped and investigated our find.

Anchor

Anchor

We had found a small boat anchor. I had grabbed it at the bottom where it hinges. We still both had half a tank of air left. We didn’t have any lift bags and the anchor was much too heavy for our dive flag float to support.  We decided a short surface swim was required to get this back to shore. We would continue to dive from there. This was my second rookie mistake of the day. In cold water a surface swim is not the most comfortable thing to do. The extra motion cools you down and what little breeze there is just makes it worse. Every time I did a long stroke it drew more water into my wet suit and the water my body has dutifully warmed up was diluted. Brrrr. As we made it to shore we decided to call the dive for the day. We weren’t cold yet but we would be soon.

Lessons learned from the dive.

  • Your priming water can be too warm.
  • Prime, prime, prime
  • Don’t swim on the surface
  • Be ready for anything and always proactively practice what you have learned. You can’t be too prepared.
  • The warm coffee felt good after the dive

Here is what I am going to do for next cold water dive. Like my more experienced colleague Mac I am going to use a jug to contain some warm but not hot water. I will put that jug in a cooler with some water bottles containing hot water. The jug will be for first dive priming. If I need more water I can cut the hot water with lake water. Also for a second dive the hot water could be used to warm up the chilly bits.  I will also make sure I have a cup. I am going to prime until I am completely primed. No dry spots. Those are where the cold water found a way to get to.  The long johns and socks worked well. It effectively made my 7mm wetsuit warmer.  My gloves were OK. I think next time I will try the latex gloves under my dive gloves. I am surprised my head wasn’t colder. My hood is only 3mm. I am thinking about picking up a 7mm hood that I could put over my 3mm. I also wonder if a shower cap would be good under the dive hood. Hmmmm.  We are going to fit an inner tube with a basket for our dive flag to be able to lift and store our trash.  We will suspend more lines from it and have a few lift bags ready.  This dive we could go to the surface easily, but on deeper dives that doesn’t always work.

Over all I think this cold water diving was a success. We have been in colder water in July, still it is only going to get colder until we get to the time of hard water. We are going to have a few more dives to try out this cold water stuff. This weekend we have scouted out a location for a river dive. On Thanksgiving weekend we will do the dive clubs “turkey dive” and on New Year’s Eve and New Year’s Day we will do the ice dive…. Yes! All in wet suits! It should be fun.

Cold Water Wetsuit Scuba Diving Tips

If you live in Michigan and you scuba dive local you are going to run into some cold water. When my non-diving friends ask if it is cold I tell them even in the summer 60 feet down in a quarry is going to be around 40 degrees. Yep cold…. not cold enough to keep me from diving. The real difference now is as the snow starts to fly all the water is cold, the air is cold and that just makes for cold. No moving above the thermocline to warm up.

So until the time I spring for a dry suit I need to do all I can to keep warm diving this time of the year.  The old… errr… more experienced Mudder divers in my dive club have offered up the following tips for cold water wet suit diving. (My dive buddy Jim actually gets credit for extracting these nuggets of wisdom)

  1. wear a good fitting 7mm full wet suit with hood, gloves and boots. (this seems obvious, but still needs to be said)
  2. wear a T-shirt under your wetsuit to help hold a bit more water/insulation between your skin and wetsuit (I don’t believe the water actually insulates. You want to limit water movement so you don’t lose heat as quick)
  3. wear latex gloves under your regular thick gloves to minimize water contact on your skin
  4. bring a thermos of hot water to prime your gloves and wetsuit prior to entry

Jim did #1, #2 and #4 two weeks ago and said he was very comfortable through his entire dive a couple of weeks ago.

Now there has to be more good tips than these. I searched the internet and didn’t find a lot new. I did find a few pointers from a variety of sources.

Before the dive

  • avoid drinking alcohol and drinks containing caffeine.
  • get plenty of rest and that you are adequately hydrated.
  • stay warm before the dive, heat loss can start to occur many hours before the actual dive.
  • wear a hat during the hours running up to the dive.
  • when possible stay indoors for the hours running up to the dive.
  • drink plenty of hot drinks before diving.
  • keep as dry as possible.

During the dive

  •  if you consider adding a “core warmer”, try both layers together to make sure you have a good fit
  • neoprene socks greatly reduce water flow
  • avoid unnecessary movements (don’t flail your arms)
  • fin slowly
  • don’t pee… it might feel warmer but, just like sweating, it’ll cool your body temperature
  • 5mm lobster claw mitts are warmer than 5mm gloves
  • neoprene compresses at depth…deeper will not only be colder but will feel colder

After the dive

  • Keep moving.
  • Stay out of the wind.
  • wear gloves and a hat as soon as you come out of the water.
  • Dry yourself off and put on some warm clothing.
  • Drink plenty of warm drinks.

Even more important than comfort is safety. Make sure you have a regulator that is designed for cold water use. If you regulator is not up to the task it can freeze up and free flow. One tip I have heard of is sliding down the hose stress relievers away from your first stage. These stress relievers stop the critical water movement around the regulator that will reduce the chance it will freeze up.

I am going to try all these steps in my next dive and will report back how they worked. I am diving in a location I did a couple of months ago so I am familiar with the site and the water temps we had back then.  I am hoping these tips work. Brrrrr..

If you have some tips please tweet me or leave a comment here! I would love to hear them. Has anyone tried Sodium Acetate Heat Packs?

Darrin’s Scuba Diving List – Tweeters (Twitter Lists) November 2009

With the new twitter list feature my twitter lists are much easier to put together.

For now I have broken them down into three groups

http://twitter.com/darrinjillson/scubabusinesses is for accounts I follow where the user has a significant interest in promoting their business. I have 20 that I am following.

http://twitter.com/darrinjillson/scubadivers is for accounts I follow where they are personal accounts of active scuba divers.  I have 20 divers that I am following.

http://twitter.com/darrinjillson/scubaorgs  is for accounts I follow where they are diving related organizations or activists related to diving/ocean issues. I am following 9 of these types of accounts.

Much shorter than what I did before.

Enjoy!

Calypso on Its Way to Restoration

Caly_diver_psoI think back to what originally sparked my fascination with our underwater world. Much of that credit has to go to Jacques-Yves Cousteau and his televised voyages aboard his ship the Calypso. I admit I have the love of the water and boating in my blood. Both my grandfather and father where lifelong marine enthusiast, but nothing was quiet as inspiring as those amazing videos Cousteau created. To see the marine wildlife up close regularly was always a treat. Much to the ridicule of my wife and friends I have retold the story of the only shows my parents would let me stay up late for were PBS Nature and Science programs with Cousteau’s being my favorites.

I had thought the Calypso was sunk and then scrapped long ago.  I am pleased to find videos that show it in the process of being restored.

**Warning – The follow videos are in French, but there is Closed Captions you can turn on. **

http://www.youtube.com/watch?v=TT1Lml855vA&NR=1 – The restoration of Calypso – Part II

Facts I didn’t know…. The Calypso was originally built in the US in 1942. I knew it was a British WW II mine sweeper, but for some reason it always looked like it was made of steel. The fact that it is wood makes sense for a mine sweeper to avoid attracting the mines it was tasked with hunting.  

On February 15th 2009 Francine Cousteau, President of The Cousteau Society, received the new Volvo Penta engines that will be equipped on the Calypso.  http://www.cousteau.org/news/engines  I have been unable to find when they expect the restoration to be complete.

A sad footnote to this restoration is the fighting that has gone on. I have no way of knowing who is in the right and who is in the wrong. There have been reported squabbles over who owns the image and the legacy of the Calypso. This has influenced who is allowed to come to its aide. To me this threatens to taint the image of this once fine vessel. I have to wonder who will be allowed on deck the day it is relaunched.
