Body check when you are on a single tank and your buddy on doubles

[Soakedlontra]

I think you have misunderstood me. The instructor agrees with you. He teaches how to rescue a diver in doubles in his tech Stress & Rescue (or whatever you want to call it) class where all his students have doubles. It's just me who would like to learn how to rescue a doubles diver even if I dive with a single tank..Underwater you cannot pick and choose whom to rescue, can you? OK the majority of divers here dive with a single tank. However there is also a fair amount of people who dive in doubles and solo divers who use doubles too.

PS Things did not turned out as I hoped for with that instructor and I cancelled the class! Now I have to start from scratch and find a different one!
