With SSI, we have a responsible diver program. I have a canister with reasonable volume in my wetsuit. If I need to pee (we have a specialty course to learn not to but it can happen), I am also trained so that I can adjust my buoyancy. At the end of the dive, we bring the canister to a special facility that treats our urine and turns it into drinkable water. A bit like the suits they have in Dune. 0 pollution, 0 waste. 100% recyclable. Does GUE do that ?
I have been trained by both and I would bet there are less coral-kicking specialist divers trained by GUE than by SSI.
Having said this, I know some good SSI instructors that focus on buoyancy and trim. One is an instructor of both agencies.
