    Nah not worth the cost and the Perdix can only handle 2 TXs anyway.

    With Helitrox, there's dives.
    Not sure what your xenophobia comment is about but Rubens is as Aussie as it gets!

    I was saying how people prefer to be trained at home then go overseas to be trained. What CCR did you complete your course on? And did you recommend the CCR or the instructor?

    Then one turns the dive, no different that a failed SPG. With proper planning, you should be able to lose ALL SPG at max penetration/depth/rock bottom, and complete the dive safely. I'd like to think you were taught this, but I'm deeply unsure.

    I do understand this. You're the first to clarify it. I would quit diving if every SPG failed simultaneously.

    I call that information overload. You will not see any of it once an incident occurs. You will rely on instinct to survive.

    No information overload for me. One glance, that’s all I need to do. No, pulling SPG to my face, pressing dive computer buttons to get the info. It’s all right there in a clear & bright display.

    SPG is there as a backup. I haven’t need it so far. Knock on wood.

    Air Integrated Transmitter:

    You’re in a mixed dive team. One is using CCR the other two are using OC. As the boat is being positioned at the dive site, the battery on your dive computer fails. A quick thinking buddy hands over his back up computer. You breathe a sigh of relief. On the descent, you suddenly realize you have AI transmitters on all three deco tanks and one on your doubles.

    That’s why your primary and backup computers are the same. And the number of people who run transmitters on their deco bottles is probably quite small.

    As Marie13 has pointed out the is very unrealistic situation.

    If your doing a dive that requires 3 deco tanks then is a pretty serious dive. Either very deep, very long bottom time, or very far penetration. This would required fairly extensive training and at this level of diving I can not think of anyone who would have transmitters on all 3 deco tanks. Yes they might have one on there back gas but they would also have an SPG. Also at this level of diving most people are running shearwater platforms and these only support 2 transmitters anyways.

    But lets give them the benefit of the doubt and say there running a Ratio or Garmin or something and you do have 4 transmitters hooked up. First of all at this level of diving you would do a pre-dive check of your gear in the morning be for even getting on the boat and part of this would be check battery levels especially if your on CC and when diving CC I every agency and every unit I can think of checking electronics is part of your pre-dive check. So you should never have a dead batter to begin with. Next if you did skip this part (which at this level of dive is already a big no no) once you did discover your computer is dead you would call the dive. You buddy would never give you his backup computer, now he would not have a backup computer.
