This reminds me of when I see all the "specialty" training courses like for drysuits. I was diving drysuits 30 years ago and there was no such thing as drysuit training. You were a diver, you had half a brain, and you knew what to do because you gave it some thought and used common sense.

Nowdays there are specialty course like "peak performance buoyancy" and "manta ray awareness specialty"....I have to confess, I just don't get it, although I am in favor of any course that keeps divers connected in some fashion.
