Well . . . . if you're using a Y block connecting 1 side to the Dil cylinder, the other to the offboard bail-out cylinder and the 3 leg to the BOV, along with an isolater, you are then able to stay on the BOV without switching out to a seperate 2nd stage. Using this setup, the BOV is isolated (via the isolator) from the DIL cylinder and feeds only from the offboard bail-out. I still have a 2nd stage with 5' hose coiled to the bail-out cylinder, but this is for an OOG diver primarily.~snip~ If you have a bail-out valve (BOV) on your mouthpiece, which has a second-stage reg as a working part of it, you may test it every so often before and during a dive, but not for any extended period of time. If you bail out to a separate bail-out bottle, then it will have a second-stage reg attached to it. ~/snip~
