It would be a very fun toy to have - rarely do recreational divers go below 80 feet. Does it have variable speed, or is it a choice between 3mph and 0mph? I would imagine it could extend dive times by as much as 1/3. Unfortunately, I could see recreational divers/snorkelers causing serious physical damage to themselves or to the habitat if they do not know the limitations of the machine or of themselves. Take only memories, leave only bubbles!
