I decided to go with both- AI wrist computer and transmitter and SPG. Eventually, I would like to have my AI computer on my right wrist, my transmitter, my SPG and a backup non AI computer on the left wrist.

In a sense, but there's more to it.This points to my main motivation for asking my question in this thread. Is there really any useful or interesting use for the data that I'm not thinking of?
and I think the answer seems to be that only a more granular knowledge of your RMV/SAC.
And you're not even dead -- imagine that -- obviously, you've stumbled across the "Mercedes" model, as opposed to the Fiat, which still burns a bit of oil . . .My 1972 Italian Scubapro SPG still works fine, but only goes to 3500 psi and fits an old 3/8" HP port. This worked fine with my steel 72s and MK5/109.

I've got 600 dives and never had an spg fail. According to this presumptive opinionated random internet poster who doesn't know anything about me, I am full of BS and not to be trusted, based on that one simple fact.Anyone claiming they've never had an SPG fail is full of BS and not to be trusted.
I’ve had an SPG fail as well. I do keep a spare SPG or two on the boat in my save a dive kit, but don’t bring it on the dive with me.Ive seen firsthand failure of oceanic, suunto and shearwater transmitters with divers. None had backup spg because they trusted their electronics. I always carry a backup spg in my bag for this reason, to loan out.
You say this like it’s a plus for the SPG. I see it as a minus, or at least neutral if you recognize the failure. A stuck SPG may not be detected right away. It may only be detected when the reading is significantly different than what is expected. Even if it is caught right away, an erroneous SPG reading is no better than a NO COMMS message on a computer screen. It’s very clear that the transmitter has failed, not always so clear with an SPG failure.SPG fails too but usually you can see that it is not reading accurately. Transmitter fails , you dont see much....
Any failure with my spg has been seen during pre dive check. Ive witnessed batteries crap out on transmitters during a dive. Ill trust an spg anyday eventhough I do like the tech stuff. I have electronic housings that costs over $10k and have nothing but problems....more inclined to using manual housings.I’ve had an SPG fail as well. I do keep a spare SPG or two on the boat in my save a dive kit, but don’t bring it on the dive with me.
