Diving Lake Meads B29 Superfortress 2005

Posted by Instructor Bill in Scuba Diving Articles and Information

b29

billAs most folks know, Lake Mead located near Las Vegas, Nevada is one of the top five fresh viagra 100mg water diving destinations in the US.

What many may not know is that in 1948 a modified B29A Superfortress Bomber sunk in the Lake (the crew survived) never to be seen again until 2001 when a local dive team lead by Gregg Mikolasek dove on it. More information available at: www.indepthconsulting.com

As of this article, the National Park Service is planning on opening this site to the general public. More than likely it will be a permitted dive with proper technical diving credentials needed to obtain the permission. I had the opportunity be a part of the dive team that dove on the wreck recently with Gregg Mikolasek. This was his first dive on the wreck since 2002.

As with all technical diving you need to plan for the depth and time of the dive. Then you must properly equip yourself to accommodate the task so that you can methodically make the dive and return safely. So, twin tanks with two regulators, bcd with double bladders and a deco bottle properly mixed for the dive plan is a minimal requirement. You also have to figure in bottom timers, back up analog gauges in case your battery operated ones fail and then last but not least dive lights, back ups, lift bags, reels and back up air decompression if needed. If this sounds like allot of work for one dive, you would be correct.

On the top side we prepare ourselves for entry. Donning our dry suits, squeezing into our tank harnesses, configuring our regulators, octos, L.P. hoses, gauges, wrist mount computers etc. We both make less than graceful entries into the water and start to check our over 200 pounds of gear for obvious entanglements, etc.

We compare our dive plan once again and with the thumbs down signal we start the initial descent. At 30 feet we perform a bubble check and then on to 100 feet where we decide if the dive is a “go” or “abort”. Today it is a “go”.

As we descend, ambient light starts to filter out and our dive lights only reflect the greenish tinted water of Lake Mead. All you can really reference is the down line and your dive buddy so we continue to descend much like a sky diver before he pulls his parachute cord, legs and arms out to control our fall. Once we reach 130 feet the water temp is at 50 degrees and dropping. The pressure has us constantly adding air to our dry suits and bcd’s to control the rate of our descent.

During this phase of the dive we start to feel the effects of the higher than normal amount of nitrogen we are breathing and narcosis becomes part of the dive (much like the feeling of a few drinks). While it is a concern, it is part of the technical divers training to handle this.

130 feet, 140 feet, 150 feet, and touch down. I am looking at my dive buddy Gregg as he points to something around my left shoulder. As I add some air to my BCD and dry suit to attain neutral buoyancy I am treated to a sight that will take your breath away. The tail of a B-29 Bomber. At first I could not focus, as it was this shadow blocking out the little ambient light that was able to pierce down this far. I was amazed. “This plane is huge”, I thought to myself.tailI saw some black numbers and rays of light glowing from the edges but at 29 feet tall the tail is just a fraction of the rest of the 100 foot plus long plane. With visibility that day limited to 30 feet you have to piece what you are seeing in your mind like a puzzle.

Since 1990 when I first started hearing rumors of a sunken B-29 at Lake Mead I was intrigued. I finally started really asking around in 1996 when I was able to acquire information from the National Park Service station in Boulder City Nevada. The documents were for the registration of a B-29 as a National Historic Site. They gave approximate Latitude and Longitude coordinates for the location and even included a brief history of how and when it went down.

From then on I was hooked. Like the guy who sits on his sailboat talking about a trip around the world and never leaving his slip, I talked allot but never really did anything about actually finding this plane. Oh, we took the boat out and with our depth finder ran a few lanes looking in the area that it was supposed to be, but at 300 feet we really didn’t do much about it. Then I became busy, marriage, children, working etc.

So, here I was, realizing a dream. A once in a lifetime dive right here in my back yard. I shook off my amazement, checked my air pressure, took a quick look at gauges and started off past the tail section following Gregg as he took the lead.

Each careful kick of my fins propelled me to another spot of the plane that I was seeing for the first time. The gunners turret had been removed and replaced with a hatch that was moved opened. I stuck my head in and pointed my light inside. The aluminum skeleton was in great shape as I imagined what it must have looked like in 1948. Over 50 years ago this plane went down to the depths of Lake Mead and here it was resting in dignity. The silver finish had been replaced by a light dusting of silt and calcium build up but the plane still looked like it wanted to take off and fly again. Pilots seat from c-pilots escape hatch As we continued surveying the wreck our next stop was the nose section. Right there was the steering yoke, instruments and what was left of the nose after it hit the lake bottom. Gregg motioned me to touch the yoke, and when I did I imagined the plane cruising at 230 MPH before it crashed on the lake surface. Each breath of air gave me another chance to stay here lingering back in history. I thought about the workers who’s rivets still held fast and the plane hanging in the air with one engine barely running as it laid on the surface above me.

more sections of the B29We swooped over to the left wing and I saw that it was still above ground. Then to my surprise, the one and only engine was there. Again it was larger than I expected. The bent propeller was at least 12 feet long. I put my arms around the engine and could barely cover the top. To think there was four of these monsters on this plane at one time. We poked around under the wing and saw one for the landing gear pieces still in tact waiting to come out. Upon further inspection I could see the tire and tread.

b29 landing gearAnother air check, 1800 psi and time 14 minutes 180 feet deep. We had to be back at the up line ready to ascend in 6 minutes. Time was flying by quickly. I gave my buddy the circular OK signal with the light and he did the same. We went a bit further out onto the wing and saw where one of the engines was ripped from the mount. The force of the plane ramming the lakes surface ripped three off just like that. It surprised me that anything was left. But here it was.

We worked our way back on the same side of the tail where our line was. Now that I was settled into the dive I was able to look into the window and see how the plane had faired over the past 50 plus years. While lying in silt, it was not silted over. I figured I was the 20th or so to see this plane and had Gregg to thank for the opportunity.

tail section b29 on landAs we passed the tail section one last time our dive was at exactly 20 minutes. We gave each other the signal and slowly made our way to the first micro bubble stop at 100 feet. As we ascended up the line I watched the tail section disappear where we left it. The chance to realize my dream, even if I wasn’t the one to find it, still gave me a sense of fulfillment.

On this day we dove with a 40% Deco Mix so we switched at 90 feet in between venting BCD’s and dry suits to control our ascent. For the next 30 minutes we went to our pre determined stops at 60 feet, 40 feet, 30 feet and then the final one at 15 feet. I was pumping my fists and celebrating this dive. I reached over and shook Gregg’s hand and voiced to him “Thanks Man”. He knew I was grateful and I think that even though he had logged dozens of dives on this plane, he felt renewed a bit too. It had been over three years since he had last dove on the wreck.

on surface with cameraWe surfaced and with my frozen lips I screamed out some sort of incoherent sentence about how cool the dive was. Gregg agreed and we floated there on the smooth surface as the sun warmed our faces on what turned out to be a perfect day for a perfect dive. For me it was also a Birthday Gift as the next day I turned 40.

Buying My First Set of Scuba Regulators

Posted by DiveMaster in The Scuba Blog

Regulators: Life Support Equipment


Q.) I’m trying to figure out the long-term cost BEFORE I buy the last major piece of equipment…my whole regulator setup. I work at a museum (no money there), and with the exception of my laptop, this will be the most expensive thing I’ve ever bought. Holy cow, is this a tricky purchase! Ultimately, I’d rather save that few hundred bucks and use it to get somewhere beautiful than blow it on pricey service or unnecessary features/ level of quality.A.) Based on your diving expectations I would recommend an intermediate package that should cover everything you need and then some. Would need to know your budget in order to really give you proper options.

Q.)1.

viagra online

How often do the various parts (first stage, second stage, octo) need serviced: annually or every XX dives? (I’ll be diving maybe one day a month in chilly Cali, and hopefully continue to do a few tropical weeks a year.)

A.) Every product you are referring to will ask for them to be serviced Annually to keep them in warranty. Atomic is every two years. With that being said, it is not the “use” of the regulator that makes the internal parts wear down. Whether being used or in storage, the high and low pressure seats are always touching with the pressure of a spring tension that over time will cause a seat to have an indentation. ScubaPro has a second stage that keeps the pressure of the seat but you have to remember to activate it. If not serviced this will eventually cause the regulator to free flow. That is good as the opposite is no air at all. Not good. Atomic has a spring that when not pressurized the tension releases, hence the 2 year service.

Q.) 2. About how much does each component’s service cost? Do some regs require more frequent or expensive service than others?

A.) Average recreational divers will need annual service, that is pretty much it. I will take my PADI hat off and tell you that many people do not annually service their regs and they will tell you that there is no problem. In most cases they may be OK but the issue here, and I hate to preach, this is Life Support Equipment. Don’t you think you are worth it? Same goes with the warranty issues for better pricing. I am rambling but you get the point.

Q.)3. I assume new parts are a pricey part of service, some regs form licensed dealers come with annual service kits for free, any tips? Many manufacturers are offering 1 to years of parts for free while others have lifetime warranty.

A.) Be careful though as they all are pretty strict on keeping within your “year” from the date of purchase to have them serviced. The kits ordinarily will run about $12 to $20 for a complete set up First Stage, Primary, Octo and Gauge.

Q.) 4. I can’t tell if the savings from an ebay or other internet purchase are worth it without figuring how much parts and service are. A first, second and octo Mares V32 Proton Ice just sold on ebay for $425. Is that (in the long term) a better or worse deal than a $800 package from a dealer?

A.)  in the case of Mares, you would receive the full warranty, (which I sure any ebay retailer will not have) and we make it worth your time by providing your first year of service for FREE, join our Scuba Club and you get 2 years for FREE. We understand that you want the best price, service and knowledgeable folks who know what you need. We try hard to work within your budget, your skill level and your anticipated amount of diving. Quite simply we try to be your LDS on the Web. Hope this helps

Remember Your First Set of Scuba Gear?

Posted by Instructor Bill in The Scuba Blog

Instructor BillHey, I remember my first gear.  It was an old Dacor Pacer that

was a rental regulator from a dive shop in Las Vegas.  The BCD

was completely faded and everything else I had was given (or

taken) from my Brother.  I guess you could say I was one of those

folks who was poor (still am) and didn’t know it since I dove

with that gear for 5 years.  I even used it when I was going to

my IDC to become an Instructor.

The Whale is Rescued by Scuba Divers

Posted by Instructor Bill in Scuba Diving Articles and Information

whale cartoonwhale in waterThe Whale

If you read the front page story of the SF Chronicle, you would have read about a female humpback whale who had become entangled in a spider web of crab traps and lines. She was weighted down by hundreds of pounds of traps that caused her to struggle to stay afloat. She also had hundreds of yards of line rope wrapped around her body, her tail, her torso, a line tugging in her mouth.
A fisherman spotted her just east of the Farralone Islands
(outside the Golden Gate) and radioed an environmental group for help.  Within a few hours, the rescue team arrived and determined that she was so bad off, the only way to save her was to dive in and untangle her…Whale_lines

One slap of the tail could kill a rescuer.

whales tale cartoon

They worked for hours with curved knives and eventually freed her.
When she was free, the divers say she swam in what seemed like joyous circles. She then came back to each and every diver, one at a time, and nudged them, pushed gently around-she thanked them. Some said it was the most incredibly beautiful experience of their lives.

whale_3

The guy who cut the rope out of her mouth says her eye was
following him the whole time, and he will never be the same.

May you, and all those you love,

be so blessed and fortunate .
to be surrounded by people
who will help you get untangled
from the things that are binding you.
And, may you always know the joy
of giving and receiving gratitude.

Is This Shark Picture & Divers For Real?

Posted by DiveMaster in Scuba Myths - Confirmed or Busted?

Dive Shark

Family on holiday in Australia for a week and a half when husband, wife and their 15 year old son decided to go scuba diving.  The husband is in the navy and has had some scuba experience. His son wanted buy generic cialis 20mg a pic of his mum and dad in all their gear so he got the underwater camera on the way.

When it came to taking the pic the dad realized that the son looked like he was panicking as he took the picture and gave the “OK” hand sign to see if he was alright. The son took the pic and swam to the surface and back to the boat as quick as he could so the mum and dad followed to see if he was
OK.

When they got back to him he was scrambling onto the boat and shaking really bad.  When the parents asked why,  he said “there was a shark behind you.”  The dad thought he was joking but the skipper of the boat said it was true and that they wouldn’t believe him if he told them what it was.

As soon as they got back to the hotel they put the pic onto the laptop and that is what they saw.

Is this for real?  Don’t know. I say Myth/  What do you think?

Why Should I Care About Full Warranty?

Posted by Instructor Bill in The Scuba Blog

Full WarrantyWell, you should.  Every item you purchase your scuba gear from an authorized dealer it comes with a full manufacturer’s warranty.

There are some online dealers of scuba equipment that are not authorized to sell by the manufacturers. Buying from online assignment help such dealers could end up costing you in the long run as the equipment you purchase will NOT be warranted by the manufacturer.REMEMBER: We are talking about life support equipment. This means that you want a company that is authorized directly by the manufacturer to sell these products.

It is that simple.

Scuba Divers Breathe Oxygen

Posted by Instructor Bill in Scuba Myths - Confirmed or Busted?

scuba tanksWell actually that is a Myth for the most part as the air we breathe is regular air that is dried, filtered and then compressed in to a Scuba Tank.  The oxygen content is about 20% Oxygen and 80% Nitrogen.  So I say Busted.

On another note, there are times when folks will scuba dive on Nitrox nitrox divermixes has a higher oxygen content.  This can be from 32% Oxygen all the way up to 100%.  the 32% and 36% blends are for Nitrox Diving where you can increase your bottom time but you are limited to a certain depth due to the effects of breathing these blends at depth.  More training is required. 

The 50% and higher blends are for Technical Diving and the higher content is for Mandatory Decompression stops.  Again special training for this as well.

Peeing in my Wetsuit?

Posted by Instructor Bill in Confessions of a Scuba Diver

I know, the saying goes like this.  There are two kinds of Scuba Divers: Those that pee in their wetsuits  and those that say they don’t.  Well guess what?  I have never peed in my wetsuit!!!!  Never!!!  Ok, ok you may be saying yeah right, but it is true.  

The idea of my pee touching my skin and then staying inside my wetsuit has never been a priority.  I will take a lie detecter test to prove it.  Even on 1 1/2 hour tech dives I have managed to keep it in my pants so to speak.  

Once I was on a dive with my Brother in law in Mexico wearing my Xcel Polarshield Wetsuit, (the one with the integrated dive hood), and  1/2 hour into the dive I had to pee.  So, I simply told him to wait, removed my BCD at 50 feet, set it down, handed him my mask and proceeded to pull the suit down over my head and down enough to pop out the shrinkage and I peed.  It was on my list of one of the most satisfying releases ever. 

If that isn’t enough to prove my point then please , try me.  I have never peed in my wetsuit.  Am I the only one?

Why Do Scuba Masks Fog?

Posted by Instructor Bill in Scuba Diving Articles and Information

scuba maskEver wonder why scuba masks fog?  Well it is allot more than you think.  Well, actually no.  All scuba masks come from the factory with a finish that makes them fog so easily especially when new.  So, all you have to do is clean the inside lens surface and outside lens with a non gel toothpaste or similar.  Want to know more?  Click on this link for more Information
