I have considerable time on rebreathers over my life span having used numerous different ones and I still find that to teach a given unit I need at least 15+ hours on that system and I think one needs a lot of hours overall on rebreathers prior to teaching them say at least a minimum of 50 total rebreather hours. plus have training and or experience in technical diving. they must have excellent diving skills and an indepth knowledge of diving physiology combined with a complete understanding of the system they are using.
