miketsp:Well I'm going to be a little politically incorrect here.
Just what is a blind diver going to get out out of a dive?
One of the basic rules is not to touch.
Without touch & without sight swimming around in a pool is no different from swimming over a beautiful reef.
A blind diver will always be totally dependent on a buddy unless equipped with some electronics / mechanics to translate depth, ascent rate and remaining air into some sort of acoustical / tactile output.
hes blind to the point were he cant read a gage but not everyone that is blind is totaly blind most blind people can see things close up or at least see somethings like shadows he can see me if i move he can see enoff to play some vidio games it just takes him alot more efforet to do so..
