Using a transmitter on a O2 first stage of a rEvo sounds like a BAD idea. One right out of the brain of a non rebreather diver (I was one and went through the same train of thoughts).Remove the Fischer cable Predator
Use my Perdix AI in CC mode as a backup computer.
Put Perdix transmitters on the 1st stages, so I can monitor CCR cylinder pressure on my Perdix.
First of all, expecting that you will check your secondary to notice that you have a zero or decreasing tank pressure when you have jumped in the water with your O2 tank off is oxymoronic (3 superfluous letters can be removed to your taste). You will not check your secondary, because you are so off the zone that you will probably pass out (and die if you are in the water).
Either prebreath you unit sitting before you jump (you will then pass out on land or deck and will hopefully be revived) or NEVER turn off your tank after your pre-dive checklist.
Of course, DSIX will tell you that's what he does that all the time (he has said it before anyway), but that's one more reason not to do it. He is a daredevil and playing Russian roulette for kicks .
Then, a transmitter is one more BIG failure point to seriously worry about. They crap out every now and then what do you do when it goes blank? Oh, you don't have a SPG to check your pressure anymore? Or you do have one but your 1st stage looks like a spider nest and is an entanglement hazard? What about you lose your balance, tip backward on the bench and crash heavily on it, breaking it off without noticing it before you jump in the water?
Etc., etc., etc.
Of course you should first take a class and listen to your instructor, who SHOULD tell you not to do any modification to your unit until after 50 hrs in the water. You will have an entirely different perpective then (hopefully)!
