I want something like that for lap swimming :D

He wouldn't actually USE it... but the idea of it would have him wishing for one! It's a gadget after all. :D

I CAN see uses for it...just not something he would use. Someone that does technical diving, meaning long waits at safety stops, could use it. They often take down under water games, magazines, etc. Our stops are just for a few minutes. So it's not needed.

Swimming for exercise is a good use though. :yes:

That'd be useful for shark-attacks! :naughty:

(I've had friends who were recreational abalone/urchin/conch/whatever divers having to stray into coves & kelp beds for extended time periods whenever they'd think a large shark was hovering nearby...)
