Just an example...Can anyone post a photo of a QC6 inflator cheater that I've heard about. I'll be inflating from one onboard tank and was told about the QC6 cheater in case that reg fails or bottle goes dry(though it shouldn't). I've heard some people just add an inflation hose to bailout bottles, but why have extra hoses that will rarely get used. I assume the cheater is just a female QC6 on one end of an inflator hose. Should be small enough to keep in a drysuit pocket I suspect.
In a cave, my left SM bottle drives:
QC6 #1 = BOV
QC6 #2 = Wing and ADV
Right SM bottle
Spare QC6
Spare BC whip for suitgas
I had the SPG fail on my left SM bottle in peacock. I turned off the valve because bubbles are annoying. Now I had to decide what to plug in where. The CCR was fine so I popped off #2 and plugged in the right SM bottle. Even though this hose was stuffed on the right bottle it was harder to do in a no flow cave than you'd expect. At least now I had a wing and ADV again. And a mostly full but shut down left bottle plumbed to a BOV. We finished the circuit we were doing and exited.
