    And that can work. If you are happy with it that is all that matters. Overkill is 100% effective. A 10 ton tactical nuke might not be the best tool for fire ant removal but it would take care of the problem. I carry a 45acp because they dont make 46's. I do stand corrected on 2 days. I mean the rest of this day and the next morning. If you are doinf AM boat dives... that sucks. I get so few vactations I have to make them count. The other thing I gain from 2 computers is I can double check the logs from them on depth, temp, time....

    Later Mon,

    Does the tank automatically leak out gas when a computer's wireless transmitter die?

    When I dive with an HP80, I have about 40-minutes of bottom time at 60-ft. Does that air consumption rate somehow change because my computer or transmitter gives out?

    Actually "they" do. "They" even make a .50. May I suggest you visit the Smith & Wesson website to take a look at their .460 Magnum and .500 Magnum? Or the Guncrafter website to look at the .50 GI?

    What you describe illustrates why many of the experienced/seasoned divers don't use that AI or remote sensor crap.

    I lost some dives on a trip because of the quick disconnect on an AI Ares dive computer. Now I use as few connections as possible. No swivels, no quick disconnects no air integrated stuff, and absolutely no remote sensors.. it's all crap that can cost you a dive trip or dives just as you experienced first hand.

    i cant say i'm a fan of wirless/electronic gizzmos underwater if i can get away without them.

    i have a standard spg .

    the thing is if the spg fails you normally loose gas-slowley but a loss nevertheless.

    if a transmitter fails you dont loose gas.

    True. However, you lose dives because no one is going diving without knowing how much gas is in the tank on a dive these days.

    loosing a contents gauge doesnt mean you cant calculate the amount of gas remaining.

    but i agree that the dive would end sooner than planned.

    What a buch of alarmist, nandy pandy malarky. They way some are talking they probably should not be diving without a complete spare set of equipment with them at all times. There is a difference between prudence and paranoia.

    That's obvious. What do you do if your primary light dies while in a cave.... You turn right? We carry 2 or 3 cutting tools, 2 or 3 lights but only one way of monitoring our gas.

    Chill bud. It's called "banter". You know, conversation.

    Most rec divers I've encountered aren't equipped to calculate gas consumption and plan a dive based on that so they are out of the water. Also if diving a team environment (yes even on a single) it's comforting to KNOW how much gas is in the tank when one needs to share his air. Without a gauge and you're donating air, no way to know. I have no idea what the odds are of it happening, however Murphy is alive and well...

    All I'm saying is there is no need for redundant gas metering. Use good equipment and ditch all the not needed connects, swivels and battery operated remote transmitters.

    From personal experience AND from what I was taught, having those extra gizmos, while not going to kill you, can be expensive (losing expensive dives) and pretty dang annoying.

    Do what you want to do, I'm keeping my stuff simple. I'm simply sharing my experience and what I was taught.

    I wholeheartedly agree with you on the "wireless transmitter" comment. I don't like the current size, positioning or placement of the current system. If they were to come out with something that didn't pose a risk of being banged or broken off I may entertain the idea. All I'm saying is that it's the only piece we dive with that doesn't have a back up. Not like it's not important.
