"advanced" divers don't want failure points, which you've done by adding the transmitter. By failure, I mean "something that can and will drain your tank the day it blows". AFAIK the 2nd SPG is not a backup for that.
It wouldn't fit nicely on the hose routing.
You don't keep watching your spg every 3 minutes, so unclipping one is not a big deal.
Finally, those things will manage to read your buddy's air instead of yours.
Well, yes that is true. My fundamentals instructor wanted me to habitually check it every 5 minutes. And wanted me to know what to expect it should show so significant deviations will cause me to become concerned.You don't keep watching your spg every 3 minutes, so unclipping one is not a big deal.
It seems a recurring theme that air integrated is readily dismissed by advanced and tech divers and I was wondering why. I could see it being another failure point or "crutch," but with a backup SPG the benefits outweigh the risk of failure in my mind.
Just wondering what some of the concerns with AI are.
