"that helps divers stay in closer contact than ever before, even while allowing them to move greater distances from each other."

Hmmmm let's see.....closer contact......move greater distances from each other....hmmmmm

Am I the only one who sees the little monir complication with this concept.

So I'm diving with my buddy and we have these nice little gizmos, and of course we decide to stay in contact while moving greater distances from each other. So I'm at one end of the wreck and my buddy is on the other when suddenly I get a text mesaage that they've got a equipment malfunction, are out of air and entangled. Well at least I can tell the coroner what killed my buddy, because of course I would not be able to span the distance fast enough to get to my buddy in time before they drowned.

The only thign this type of device will do is promote bad diving habits among that group of already complacent divers.
