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.
My back up computers are not the same.
 
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.
Thank you. Just getting clarification for other would be technical divers that rave about transmitters. Divers do use cheap batteries of various quality. My point is you can ruin an expensive dive if you rely on transmitters.
 
I dive transmitters all the time and they've done fine. Rebreather, side mount, or back mount I find them to be reliable and convenient. If you don't trust them, then don't dive them. The right wrist has the right sensor as its primary and the left wrist has the left sensor as its primary. I carry two spare SPGs to cover me if I can't sync, but I can't remember ever having to resort to them.
 
I dive transmitters on all of my tanks and my transmitters are connected to both my primary and my backup computer so if one computer fails I still have readings from my transmitters and yes I use up to 3 transmitters at a time with my Oceanic Computers. The main reason that I will be switching to Scubapro instead of Shearwater in the next year is the lack of support for more than 2 transmitters. In over 20 years of using transmitters I have not had one fail yet but I do make sure that my batteries are changed before they go dead. I have seen more failures and inaccuracies in analog SPG's than I have in transmitters. Also remember that a mechanical SPG will wear out and become gradually less accurate as the Bourdon tube loses its elasticity from repeated use, an electronic transducer will not although everything will fail at some point! In the end it all comes down to personal preference, I prefer and trust the transmitters will work if properly maintained while some people do not. And yes I will have easily over $2000 in my new computer set up when I am done but as long as no one tells my wife I will be ok!
 
You do you. Some of us like our technology.

I do this Perdix AI and Cressi SPG Digital Console. Neither have failed me on a dive.

He's well known. But how do you justify that statement since you only did an Advanced Nitrox course which is academic. The majority of the course was learnt in the Nitrox Diver course. The other problem, people suffer from xenophobia and don't trust foreign divers to train them. Just like shoppers are brainwashed into buying name brands.

My first OW dive instructor was an Australian, since then all of my instructors have been foreigners. :)
