The curious case of AI. Do you use a back up SPG while using AI?

[amado_sarhan]

What about get connected to the divers you're guiding? What do you think of that, to be able to read out their levels?
In the poolbusiness everything goes to bluetooth connecting and wifi, but this also comes with a lot of troubles. Takes a lot of time to convince people it's not that stable as wired connections.

I do not instruct or guide anymore. But that's an interesting question. I can only talk about myself, if I was guiding or teaching I would expect the student/diver to monitor their SPG and report at pre-agreed levels or when I ask for it. I would not be constantly monitoring their air pressure levels.

I agree, I myself am still skeptical and that's why I was asking the community

Thanks for sharing!

I only use a transmitter - no spgs at all.

Even on stages?

I only use a transmitter - no spgs at all.

And by no SPGs at all, I understand that also includes your cave diving and on stages. Thanks a lot for sharing this!

I've removed by backup SPG from my kit and keep it in the bag on the boat. I have one SWIFT transmitter and two Shearwater computers, a primary and a backup up.

This topic has been hashed, re-hashed, re-re-hashed ad nauseam.

Start here for some additional reading:

Spg, AI, both

Before AI did you dive with 2 SPGs? That is where the redundancy argument falls apart. If AI failures were common today, we’d undoubtedly see a trend away from AI. Instead, we see the opposite. The vast majority of dive computer manufacturers offer AI. For the most part, diving with both AI...

Spg backup to transmitter

backup spg to transmitter Hey just to sum it up i am a pretty experienced diver And i am just starting to dive sidemount and i have ordered the perdix 2 and 2 swift transmitters but i was thinking about if i could swap the spg with the transmitter that way i don't have a annoying bulge in my...

SPG with AI computer?

So I recently picked up a like-new Oceanic Atom 3.1 and transmitter, which looks like they've never even been used. Tested the air integration out on a tank at my local dive shop, and it seems to work fine. My wife and I will be further checking out all our scuba equipment in their pool prior...

I see. The more replies I see like yours, the more I feel that I just came out from the 80s

I'll go through the links you shared. Thanks for sharing!

Never ran an SPG ecxcept for the one on the rent-o-crap rig I had for my OW "training".

Run dual xmitters to a SW NERD on second and a Perdix on R wrist (that was a habit when I was wearing a Teric as my dive trip watch no the left, but it's remained.

Transmitters only for back gas. Buttons for deco.

Only AI on O2 and main 2 diluents; only SPG on other mixes / stages that I am not planning to use except for BO

Two transmitters for sidemount OC cave diving, one on each tank, both going to a Perdix on each arm. For CCR, I have one in O2 and one on dil. BO has SPG. On CCR, both transmitters go to Perdix on right arm. It was already set up for transmitters from OC diving. Even though my CCR came with a Petrel 3, I never bothered to set the AI up. I prefer having transmitters on my backup computer.

Button gauge on O2 bottle
SPG on stage bottles.

Here's a good writeup on the subject,

Personally I only use Transmitters, specifically 3, 2 for sidemount bottles and 1 for o2 bottle (sidewinder). I have had a transmitter fail, once, in a cave. The OPV blew, shearwater replaced in free of charge in 5 days including shipping.
