Sanctum Critique with some good diving messages

The Image via WikipediaI just came across this review of Sanctum.  He's not very positive about the movie but his analysis is interesting and though provoking.  He compares the recklessness of one of the characters to
being a serial killer.  Spolier Alert!!  He tells all, but, if you haven't seen the movie he also suggests an educational way to watch it that might make it better.

Great Article on Breathing

Bronchi, bronchial tree, and lungs.Image via WikipediaHi folks,

I came across a site on dive fitness that looks really good.  I like this article in particular because it shows how developing improved cardiovascular fitness through swimming can help raise fitness levels in a myriad of ways.

Let me know what you think.

German Fit 2Dive

Diving pictureImage via WikipediaI came across this German fit2dive site but, due to bad planning, I can't vouch for the content. Does anyone know if it is any good?

Rocket Man!

British UGM-27 Polaris missile on display at I...Image via WikipediaOkay - here's an upfront spoiler ... nothing bad happens in this story. It's just an incredible tale that I find to be extremely funny! Think of it as a sorbet between more serious fit2dive meals. I hope you guys enjoy it.

A few years ago, I was invited to go on a "bug hunt" off North Carolina. For the uninitiated, this refers to a lobster hunt but, in North Carolina, the lobsters are unlike any I have come across. For starters, they are HUGE!!! Recently we served 6 of them to 22 fellow divers and friends and everyone was stuffed to the, uhm, "gills"! It is not uncommon to get 6 to 7 pounds of tail meat off one of these monsters. The other wild thing is that these babies run across the ground in the open like a pack of dogs. If you want to experience it for yourself, call Bobby Cox at the Diver Down in Morehead and tell him you want to go to the "Live Bottom" site. Bring a BIG goodie bag and LOTS of air! Anyway, back to the story....

This was new to me so I asked around about technique. Some said, catch them in the open and jump on their backs(??) (actually that turns out to be the right answer for reasons that will become obvious). Others advised the use of a wire loop to catch them by the tail and haul them out. This was my naive preference and I headed overboard with a dayglo green loop stick that, in retrospect, doubles as a newbie identification device!

As I headed down the line I ran into the guy, whom I will forever remember as Rocket Man, at about 20 feet. He was straining to get down and obviously seriously buoyant. In his exertion, he was blowing huge clouds of bubbles that completely obscured the view below. I flashed the OK sign and got one in return. Shrugging internally I headed down for my quarry.

The bottom was about 136 feet down (kind of deep for a lobster hunt but that's where you need to go to get big ones) on a sandy plane dotted with coral upgrowths and overhangs. To my immediate right was the biggest lobster I had ever seen. He was probably 8 to 10 pounds but, to me, he looked more like 20 to 30! Wasting no time I followed my instructions:

  1. Gently position the wire loop behing your lobster. - Check!
  2. Waggle your hand in front of him so he backs up into the loop - Check! (I was SOOOO good at this!!!)
  3. Pull the loop tight to capture your lobster!
OK - here's the issue with number 3. When you pull the loop tight you effectively change the species of your prey. Before pulling it tight, you (most likely a homo sapiens) and panullirus argus are locked in battle of wits in which you should have at least a slight advantage. After the pull, you basically have a "cannis familiaris in a verda", loosely "dog on a stick!" The lobster, quite understandably went completely nuts thrashing me all over the place. Before I knew it, he was gone, I was exhausted and my bottom time was up.

Reaching the boat, I found Rocket Man on board, dry and decidedly pissed off. After shedding my gear and grabbing a sandwich I went over to chat. I learned that RM was a spear-fisherman from Florida visiting North Carolina with his family. He told me his first dive had been aborted coz he couldn't get down. I sympathized and asked about his gear. It turned out that he was wearing a 7mm 2 piece wetsuit (tunic over a farmer john). "Wow", I said, "That's a lot for out here inthe Gulf Stream, I'm diving a 3 mm. How much weight did you use?" Expecting an answer of 22 to 28 lbs given his height and presumed weight, I was blown away when he answered "A lot! 14 pounds!"

I think I just stared dumbly at him for a second or two because he asked, "Why? Isn't that enough?" We chatted for a few minutes and agreed that if he planned on doing anything other than snorkeling on the surface, he was going to need some added poundage. He set off to pass the hat for extra weights and, by the time we were ready to splash for dive two, he had everything that wasn't nailed down attached to him. As soon as the pool was open, he was off! I remember thinking, "Dirt dart away!"

About 5 minutes later I entered the water to continue my display of lobstering incompetence. I wasted another dive messing around with the lobster scaring device and headed up the line, a minute or so into deco, empty handed once more. At about 50 feet I saw something rising out of the depths below me passing the other divers on the line. It was Rocket Man! He was just off the line and in an uncontrolled buoyant ascent so fast that he was passing his own bubbles leaving a trail like a Polaris rocket coming out of a sub! He flew past me at about 40 feet making no obvious attempt to vent his obviously overinflated BC. At 20 feet he grabbed one end of the hang line and promptly pulled all of the other divers (who were neutral) up with him. At the very last minute, he tried to flare and contacted the hull of the dive boat face up right on the center line, spread eagled - like a bug hitting a windscreen - before spidering his way to one side, popping to the surface and getting out!

When I finally surfaced almost 10 minutes later, I expected him to be dead.
  • He'd gone in 5 minutes before me.
  • He'd began his ascent at least 5 minutes after me.
  • He was breathing air and I was breathing EAN 30.
  • His ascent was far too fast and there was no attempt at a safety stop.
But, as with my choice of lobster harvesting techniques, I could not have been more wrong. He was fine. Breathing, alert, refusing O2 and bitching mightily about the crappy dive, crappy fishing and crappy ascent. I have no idea why he wasn't comatose or at least blowing pink froth. Lucky doesn't begin to cover it. Maybe he got into trouble later but he was fine when he pulled out of the dive boat parking lot 20 minutes after we docked.

So, that's the story of Rocket Man! I wish I had a picture of him on the bottom of the boat - it was priceless! This will have to suffice ....

Out of Gas Too!

In my last post, I told the story of Steve; a tremendously likable fellow who ran out of air at 100' and then got into all kinds of trouble related to his poor fitness level. Sadly, Steve died of a heart attack while diving just over a year later. This posting is about an incident that occurred just two days after Steve's initial incident. Same boat. Same ocean. Different guy - let's call him "Brian".

Brian joined our boat after Steve bailed after his fright that Monday. They were friends and, like Steve, Brian was a local diver with lots of experience on and under (?) those waters. As heavy and vivacious as Steve was, Brian was the opposite. Quiet and thin, he showed up on Wednesday morning and quietly got to work putting his gear together properly and efficiently. After the problem with newbie Steve, a couple of divers took a moment to check in with Brian and one checked his computer on the sly to confirm the number of logged dives therein - 40. The only weird thing about Brian's set up w
Trevor Jackson returning from a dive on SS KyogleImage via Wikipediaas that he would be diving in a shorty wetsuit. Kind of tropical but the water was warm and we were further offshore in warm gulf stream waters so it wasn't ridiculous.

One of the many instructors on the boat, who was diving a rebreather, took Brian under his wing for the first dive. They splashed a little after 8:30. I was right behind them.

The dive was to the wreck of the Schurz - WWI German battle ship with a great history. It's always an incredibly beautiful dive and I highly recommend it. We were tied into the bow and most of the divers set off down the wreck, dodging the plague of lion fish that have taken up residency there (and almost everywhere else in the area). I turned around at the beginning of the afterdeck and headed back to the anchor. About two thirds of the way back, I saw a flash of movement up and to my left. Brian was making a run for the anchor line at 45 degrees - very fast, no bubbles! I took off after him.

One of things that's incredible about diving with military, rescue and law enforcement folks is their situational awareness. When we get back on board after a dive, discussions cover not only what each diver experienced but a pantheon of observations about what else was happening on the wreck, reef or whatever. This day Dave Gulley, an EMT from St. Louis and incredible diver, spotted Brian about the same time I did. Closer to the anchor line, Dave reached him at 80 feet and immediately put him on a regulator. I joined them as they reached the line and shadowed them through the ascent. His rebreathing dive buddy, joined us at the same time - Brian had all the help he could hope for and then some.

Back on board, Brian joined us by the coolers on the sun deck. What we heard, blew our minds. Brian, it turned out, was Steve's dive buddy. They had both just started diving and, like Steve, Brian had 6 dives. The 40 dives on his computer were from another diver. Although Brian competently set up his equipment, he forgot his weight belt when he jumped overboard. But he was so skinny, he sank like a stone until his aluminum tank started to empty at which point he had to work to stay down. This meant that he used air much more quickly on the way back than he had on the way out, though, in fairness, he had probably turned around too late as he followed the dive profile of a diver with hours and hours of available gas. But the thing that really amazed us was that Steve hadn't told Brian, his buddy, about Monday's near-death experience or the reason for his passing on that day's diving.

As with Steve, we talked him through the errors and helped restore his confidence by shepherding him through an easy, better managed dive on dive two just before lunch. It was a good end to what could have been a terrible day but that night the more experienced divers had a long talk about our role in both incidents. With respect to Brian the conclusions I came to were:

  1. Our examination of Brian's experience was insufficient.
  2. Pairing a new open-circuit diver with a rebreather diver (even of great experience) is a real challenge and probably not advisable.
  3. Failing to share your incidents denies your diving buddies of the opportunity to avoid your mistakes. It's more than a little negligent.
  4. If you are going to take responsibility for another diver, of any experience level, take the time to check their equipment (like we were all taught to do in open water class) to make sure it's in place and secure.
  5. Always discuss your gas management plan with your buddy; if only to make sure he or she has one. Whether it's a third in , a third out and a third for reserve, or head back at 1k and on board with 500 psi, or whatever, it is arguably THE most important plan.
Ok, so what about fitness?

Mentally, none of us were fit because we didn't have the right info - garbage in = garbage out. Cave and technical divers use rigorous checklists because they ensure that the garbage in problem is solved which allows other aspects of mental fitness to take shape. As for Brian, his inexperience greatly impinged on his physical performance because he overlooked a key piece of equipment and made the wrong move when out of air. He was surrounded by divers with plenty of gas but he ran for the surface. That's panic and decidedly unfit. On the positive side, the rescuers didn't panic and several folks were aware enough to spot the problem and react appropriately and very quickly.

Physically, we looked a lot better. In spite of Brian's buoyancy, Dave's fitness ensured that he had no problem managing the dive through the safety stop. The more experienced divers had lots of air because they were skilled and therefore efficient in the water. Finally, Brian's own fitness level assisted in his rescue.

Two divers, two days, two similar incidents, two primary rescuers, two good outcomes, several important lessons learned.
