I've had the experience of diving with my GUE instructor when he was doing some shakedown stuff with his RB80. Although I didn't know enough about the unit to do any critiquing of how it was working, we did practice S-drills with him on the dive, and with the exception of the rather dramatic toss of the loop, they were the same S-drills I was used to.
The system's pretty solid, in that it accepts all these upgrades without changing the basics. One of the things that keeps me a pretty committed DIR diver.
Kind of like
this Lynne? I concur & like the way how this is based on and differs very little from the same immediate action S-drill we all learned in Fundies (and which is why I'm reluctant to train on any other rebreather system). . .
