Scubamarketing, LOL, might as well offer $500,000 if not going to give any hints as to where the camera may lie. No lat long? No specific vicinity, no potential depth? New Zealand? Not the biggest island in the world but believe one would still need a location hint a bit less broad.
I think the reward its-self is just a slimy marketing gimmick. Not enough information presented to make a serious go at finding the cameras.
Completely agreed, just sharing since it's relevant to the OP I don't work for or represent the company despite my username (It's Saturday and my one day off, otherwise you'd see my LP sig)
