LOL I agree whole heartedly.
I wish I could try an M48 but I'm not all that motivated to go and buy one as a volunteer diver in our local aquarium. Its fun, I enjoy the experience. Just dislike the AGA with surface supply hose. Seems rediculously over complicated to dive in 18ft of sand and carbon filtered water (i.e. super clean). And I think its a rather complicated approach for open water 'sport' technical diving.
The primary purpose of the AGA mask in the Seattle Aquarium is for communications. It's the best mask for the interactive diver program.
