When diving with an AI computer do you also use a Redundant/backup analog pressure gauge?

[WI Scuba Dave]

Absolutely! And I’m glad I do. I’ve lost AI a couple of times yet had everything else on my computer still functioning properly. So I was able to continue the dive.

 

[OMyMyOHellYes]

Nah.

I'm a redundancy fetishist, but the SPG stays on the surface in the bag.

OMMOHY

 

[OMyMyOHellYes]

Then again, could just bring back the J-valve concept...

I bought a reg set that came with a SPG so I left it attached as a backup to my ancient Cobra 1. I'm on vacation and I don't want to miss these dives but it'll probably come off back home. However, my computer is older than my kid who is now able to dive with me so it may stay put.

 

[Dutch-Diver]

YES, the magic word is Redundancy.
Lets be honest, you probably have a spg already so use it

 

[GDHLEWIS]

Yes have my old SPG so carry that as redundancy, dont use it often just check a few times during the dive to ensure Im getting accurate readings. I do see why people do not bother if you have a reliable AI, but for me doesn't hurt to have a back up

 

[rongoodman]

Not any more. I bring an SPG and hose along in case of an problem during a trip but I've never seen an issue with my Shearwater transmitter and computers.

 

[Cthippo]

Nope. I use a console computer and if it goes out then I am done until it gets fixed anyway. I should have a reasonable idea what is still in my tank, and as soon as my other regs come back, I should also have a pony tank to switch to if needed. I feel this is adequate mitigation for a gauge / computer failure at depth.

I use the @rsingler setup. It gives me a button gauge and my transmitter on my chest (great signal stability). Great for checks on the boat, and maybe helpful on a failure.

YMMV
