This Small Wristband Compass will help to keep you from missing the boat - literally. Diving without a compass is never a good idea. This small (about the size of a quarter) analog compass slips onto most standard watch bands so you’re prepared for a dive any time. Made for diving, this compass will stand up to the pressure and perform. No more, ‘Where’s the boat?’. You’ll be able to navigate on your own (well, assuming you take a heading when you get in the water).
