Someone on this thread mentioned that he thought an instructor should have experience in at least 4 different environments. What would be examples of those 4? Like warm water, cold water, fresh water, and my dry suit has icicles on it cold water? Or would it be more like pacific cold, pacific warm, atlantic rough, quarry fresh or something along those lines?
I have followed this thread with interest since it started. I'm an SSI Dive Control Specialist instructor. SSI's Dive Control Specialist is a combination divemaster/assistant instructor rating.
When I'm conducting an Open Water Diver course I like to introduce a variety of scenarios in the classroom as well as in the pool. I want new divers to appreciate the idiosyncrasies of different enviornments: what special skills will be needed, what considerations come into play when planning the dive.
If (knowing what I know today) I were a non-diver signing up for my Open Water Diver course, I would hope that at some point we would discuss and prepare plans for a range of dives with special challenges, for example:
Warm water, great viz, steep wall
Cold water, shore entry, strong tidal currents
High mountain lake, cold air, heavy silt bottom
Open ocean, free ascent with no visual references
_
So that's a possible four. Not that four's a magic number, we could concont more.
I think I'm a better instructor for having experienced narcosis (both pleasant and dark), open-ocean pickup skiff dead in the water and drifting away, regulator freeze-ups, and silt-outs. Lessons learned the hard way, in some cases.
I was initially led to believe that sharing my stories in class was important. These days I don't usually tell those stories. Instead I try to minimize the number of lessons my students will have to learn the hard way.
