In terms of using Wireless transmitter on trimix diving, do you really use it? is there a mixed gas diving using multiple wireless transmitter based on different mixes he carried.Is there or what dive computer uses more than one transmitter for a different mixed.

I'd dare say that 99% of technical diving computers are not air integrated. The only one that I know of thus far is the Suunto HeliO2. Suunto HelO2 Blue to black and back
In gerneral, most Tec divers don't use the wireless computers especially at the Trimix level. In my mind, the two best Trimix computers on the market are the Liquivision X1 or the Shearwater Predator. Both are tate of the art and can be used with Rebreathers if you go that route down the road (with diving Trimix, will be sooner than later).
The only thing the transmitter is doing is transmitting the tank pressure to the wrist gauge. It's the gauge on the wrist that's doing the computations of decompression status. And yes, there are gauges you can buy that will compute decompression for helium mixes, and gas switch to your deco mixes. The Liquivision and Shearwater computers will do this, but at least the LV doesn't have a transmitter (yet).

I use a wireless transmitter on my doubles and trimix. I also keep a regular SPG with a hose as a backup. I also use a wireless transmitter on deco bottles... Because I have more than one transmitter.
The computer I use that reads the pressure with the wireless transmitter however - I don't use in computer mode. I use it in gauge mode, and I use a shearwater computer for running my dive.
Thanks for all your opinion. Does the Suunto Helo2 come with one transmitter only?
Usually wireless AI computers only come with one transmitter. However, you can buy more transmitters.
Tech divers, and I'm not one of them (yet), don't have need for AI computers (actually nobody really need a computer much less AI computer) because they tend to plan their dives down to a gnat's ass: I'm carrying so many tanks with so much gas, I'm going down to maximum depth of XXX and stay there for YYY, then I'd go up to this depth XXX and stay there for YYY, then I'm going to this depth XXX and switch to Gas A and stay there for YYY, then I'm going to this depth XXX and switch to Gas B and stay there for YYY. Or I'm going to this depth XXX and go in AAA for this long YYY and then turn around at ZZZ pressure reading. They know what their air consumption rate(s) is(are) and they know how much gas they're going to bring along and/or having staged along, they know what kind of gas to be used when and where. They can plan their whole dive and write everything down on slates so that they won't forget and just follow that dive plan.
Rec divers tend to go, "Hey, look at that cool thing at 50ft, let's go check it out!!! Hey look at that cool thing at 70ft, let's go check it out!!!" Hard to do a detail plan for that sort of diving.
When you start getting into big dives the number of failure points goes up and up, not uncommon to get stuck last minute having to change an o-ring out or swap a reg or something because out of the 4+ regs your taking one has a malfunction or an o-ring isn't seating or your primary isn't striking or a backup flooded on your last dive yadda yadda you get the drift
All of these things slow down the time it takes to get in the water and do your dive
I've dove with guys with wireless and several times it caused serious delays in getting into the water - is it because wireless is evil and will kill you? no, but its another thing that can go wacko on top of everything else.
I've stood in little river basin for 30 minutes waiting on my buddy to come down, he never did, wireless problems, this did not contribute to my fun it sucked
Too many times I've screwed around on the surface helping a buddy turn regs on and off while he fiddled with a computer, very annoying
one time too many I had a buddy bolt in the middle of a dive because he couldn't read his pressure and decided "he had to get the hell out of there" don't care to elaborate but it wasn't a cool situation
I know of one case where a buddy team got seperated, wireless problems popped up so that the survivor didn't know how much pressure he had to search for his buddy, he made it out his buddy didn't (note I don't blame the wireless for the death or the buddy, even with an spg the outcome may have been the same but... with an SPG there would have been no doubt about remaining pressure)
My attitude now is, if I see a wireless transmitter and no SPG, I'm not inclined to ask that person to dive with me.
Wireless on rec dives, sure, one less hose etc its a cool feature
technical dives.... well like I said, if I see a transmitter and no spg thats not a dive I really want to be on, I hate the things, another "toy" to screw up that is a fix for nothing - if its not needed don't take it, stick to SPG, you don't have to worry about its battery dieing, flooding, or not talking to your computer.
I use one.. not doing technical diving, just trimix and different gasses on the accent.
With an older system, used to have all sorts of failures... but this last year... with a new system, it has worked perfectly. But my dive time is way to important to me to stop diving for a transmitter faulure, so I have a spg on my main reg, and small gauges on all my small bottles.
Doing essentially deep recreational diving, I only generally know the depth and the plan, so using a computer to keep track is kind of important.
The wireless is not needed during the dive, but it helps later on setting up for the next dive as you have a record of your SAC rate and actual gas usage during the dive. You can actually see what effect shoot a fish has, or swimming against a current...
