Using ai computer on deco stage

[barilhu]

Does anyone use ai transmiter on deco stage tank?

I currently use a Galileo Sol with transmiter on my back gaz. I also have a SPG.

On my stage bottle I only have an SPG and would realy like to control my pressure from my computer.

Any suggestions

I think you might be hard pressed to find a tech instructor that would advocate AI for anything. For me, simple is the best.

How does one "control" their gas via the computer?
Read the remaining pressure via a transmitter perhaps....

I cannot think of any huge advantage to having a pressure transmitter on a deco/stage bottle.

Without sounding too negative, maybe think why you need the AI on your deco bottle? If the bottle is for decompression then you’ll only be breathing off it when you are at or between your stops, so looking down to the spg shouldn’t be that tough (you need to look to check it’s the right gas after all), and calculating SAC etc if that’s what you want should be simple as you are at fixed depths for fixed times. Seems an extra complication / failure mode for very little return.

I guess if its genuinely a stage bottle and so used as a travel gas or somesuch you might get some benefit but that sounds dubious…

There was a thread on this topic a year or two ago. I was surprised at how many advocates for using this approach participated.

About 3-4 years ago, I did some dives with a buddy off of a boat on which all the rest of divers were doing R&D on a computer that would not only read the AIs of all the gases being used, it would sense when the diver had switched (I suppose through its changing pressure) and make the switch automatically. I don't know what brand/model they were testing. From what I overheard after the dives, they felt it was working.

I don't use AI for tech diving myself, but there are people who do it.

I have an AI transmitter on my recreational reg, but I'm always concerned that it will get snapped off by hitting something. Once I almost accidently picked up the rig by it when reaching for the tank valve. I can't imagine putting one on a deco bottle as much banging around as they get.

I'm a little different about gauges on deco bottles anyway. I don't prop the gauge up on mine. I leave it against the tank out of the way. I know before the dive whether I have enough deco gas. There's no need to actually look at the gauge in the water, except out of boredom. If you do unexpectedly breathe it down, just switch to back gas.

my deco bottles just have button gauges on them, stages have real pressure gauges. For me the transmitter would cause the top of the tank to have way too large of a profile. With the normal hoses going straight down, you'd have to run the transmitter vertically which would make me nervous as hell with how fragile they are. If you could get it turned down and a button gauge on top I guess that could work, but I don't know of many that are small enough to do that with unless you have the offset Genesis valves.

For me with deco bottles it's always the "is it full? Yup, let's go". I don't look at pressure gauges, I make sure I have at least 2x as much as I need, and make sure the bottle is full at the start of the dive and when I pick it back up, don't need much else out of it, and since you aren't changing depths on the bottle, you know what your SAC rate is really easily.

All my regs are logistically equivalent. Stage or deco, it doesn't matter. Comes in super handy if you have a borked reg and need to swap it out quickly or your buddy needs a reg. They're all the same, so no problem.

I seldom look at deco pressures as I know and have planned for what I need. That said, when the pooh hits the fan you want something reliable and AI dont fit the requirement, at least for me.

In the end you have to make your own choices and live with the consequences, there is no wrong or right.

I have never seen this, but I am told that some people who use AI transmitters have them dangling from short HP hoses for that reason.
