I am interested to know what types of dive cannot be done without AI?
The ones where you don't use an SPG?
This illustrates the difference between recreational and technical thinking.
So... you don't need to sync the AI? You don't need to program the gas?
For tech; you wouldn't need to repeat that process for every gas/cylinder used? You wouldn't need to apply safeguard procedures, as an error in that setup would seriously compromise diver safety?
You don't need to formulate/adopt a protocol in the event of AI electronic or battery failure? Of sync failure...
So realistically, on "average", how many tanks is a tech diver carrying? Doubles and a slung tank? Twin sidemounts? My understand is the most extreme dives are only carrying 5 tanks. And that's probably not happening that often. I would think at that point a diver would be better off just going to CCR with "AI".
I don't want to pretend I know tech procedures, but aren't you programming multiple tanks into your computer anyways? Why would it be so much more dangerous if those "already programmed tanks" also provided tank pressure on the computer screen. Another safety feature of AI is the computer won't let you select the wrong mix for the depth. Which we know is a big risk in technical diving. That doesn't stop someone from doing it, but if they're narced out of their mind, perhaps the computer will help them to catch their mistake. Even better would be an alarm when the computer senses a gas is being consumed that shouldn't be. Might just save some lives. And again, automatic switching on the computer would be innovative. Followed by a simple confirm.
As far as backup goes, perhaps a button SPG could be added to the tip of the SW transmitter so in the event there was an electronic failure you could still get a gas reading. Maybe since SW is so awesome they could build the most reliable transmitter ever.
Whatever the case, tech divers seem like a group of people who could figure out how to implement the best/safest procedures.
Btw, with my computer I've only synced it once. The first time. As soon as the transmitter is pressurized the gas automatically shows up on my screen. I program the mix, the tank size and the rated tank pressure.
