    Bluetooth Dive Computer Yet?

    For the dive computer to desktop or laptop link, Bluetooth would work fine. For underwater use, that 2.4 GHz signal is not going to work worth a crap.

    Scrubbing with EANx

    I was poking around in DecoPlanner and found that if you have your heart set on carrying one deco bottle, you can get a significant time advantage by first planning the entire dive on your backgas, then adding a deco gas with an MOD that is the same as the depth of the deepest stop the program...

    Using a twin cylinder?tanks. .

    Big gas capacity makes sense if you are using Nitrox. A dive to 50 feet with EAN36 could be _very_ long and still be a no-stop dive.

    How Dangerous is Scuba Diving?

    My take is that it is not dangerous. From what I have read in incident reports, a large portion of the people hurt or killed were basically asking for it.

    Sound Off ! Familiar with the term 'International' referencing 'yoke style' regs?

    This thread is the first time I have heard of the term as applied to yoke connections.

    Nitrox on OW course

    Taking the course can only do you good, but there is no point in using EAN until nitrogen loading is the limiting factor on a dive. Most newly certified divers consume gas too fast for nitrogen to be an issue.

    Diving with argon and hydrogen mix

    You may already know everything there is to know about it since Argon and Hydrogen are more narcotic than helium. Argon is a pretty slow gas and is more narcotic than nitrogen.

    Argon Cannister Q

    You also need some pressure. I have not tried shield gas deeper than about fifteen feet. I am told the problems with acid show up at greater depths. I would imagine it is a partial pressure thing, so diving with pure CO2 would get the diver into issues shallower than a mix.

    Argon Cannister Q

    This happens when people use welding shield gas for suit inflation at something other than a rather shallow depth. CO2 is actually pretty effective shallow.

    Interesting stat in Accident and Incident Forum

    The chances are somewhat reduced. Wanting something to happen and it actually happening are quite different things. It does indeed - and a considerable amount at that.

    Many of those tables are riddled with mistakes. I have never a found a table that was completely correct.

    Talk Radio... underwater...

    At medium wave frequencies, it would take a heck of a receiver to get anything useable deeper than about an inch. Maybe you could put the receiver on a float and run the audio down on a wire, although that would probably involve putting something more than the usual ferrite bar up as an...

    Is there a Nitrogen Loading Equilibrium Point?

    Sorry, I do not walk around with a file of everything I have ever read. There were two people in the same incident that I can recall right off. An STG and a tech rep were working in a pressurized SONAR sphere on a destroyer and got themselves bent. It was in one of the Navy safety pubs...

    Is there a Nitrogen Loading Equilibrium Point?

    If we are swapping anectdotes, people have been bent after eight hours at 20 feet. Your mileage may vary. May cause airsickness in diabetic pregnant chickens.

    Is there a Nitrogen Loading Equilibrium Point?

    I spent some time fiddling with various deco software and a dive computer simulator and found that they all said I was unbendable at 12 feet on air. It took a really long time to get bent shallower than 20 feet, but it can be done.
