Tech diving involves multiple tanks. Unless you put transmitters on every bottle, the only information your AI computer will gather for you is from the tank(s) you have your one transmitter attached to - likely your backgas. It won't tell you how much gas you have in your various tanks, it won't tell you your SAC rate when you are on a stage bottle or on deco. And it certainly won't tell you *air* time remaining on those tanks or dive time remaining. All benefits that AI proponents tout.
For tech divers, AI computers would be of limited value anyway. Why bother getting it if the so called benefits only extend to recreational dives?
I have a wireless AI computer. I have just started Tech training.
I am not planning to install my AI transmitter on my Tech reg set during training, as that is not part of the configuration my instructor has specified. But, I have already completed the classroom portion of the training, so I have some idea of what we are going to be doing and how we're going to do it. And I will be using my AI computer (without the AI portion) during training - using it in Gauge mode.
As I look forward, it SEEMS like I MAY choose to add my AI transmitter into my configuration later. The reasons I think (now) for that would be that it would give me additional monitoring and data collection on my usage of my back gas. The fact that I would not have the same info for my deco gas does not take away from the value of that info for my back gas. Plus, I anticipate that back gas consumption will occur while I'm focusing on other things. Reviewing the data to see what my consumption was during the different parts of a dive seems just as useful after a tech dive as it is to me, now, after a rec dive. OTOH, when I'm using my deco gas, I expect, generally, to be doing nothing but "hanging". So, while finely detailed consumption data might be nice, I don't think I would get as nearly as much benefit from it as I would from back gas consumption data. For deco gas, I will know start time, pressure and depth, and end time, pressure and depth, and I think that will probably be adequate deco gas data to facilitate good future gas management planning.
All that said, I am looking forward to completing the training and getting (hopefully) lots of real world experience with my tech rig and seeing how my current projections of my desire to use AI actually hold up over that time.
