This compass is more than just an accessory for your dive gauge console system. It's actually a dual purpose compass that no diver should take for granted. The convenient side window allows quick reference of large, easy-to-read bearing indicators on a luminescent display for gun-sight accuracy. Or, for divers who prefer relative navigation, the ratchet bezel can be rotated easily even with thick neoprene gloves.
Best compass! Great for instructors or sharing with a buddy. I have mine on a clip or retractor so its easy to use and pass to others. Compass is a tool every diver should have for better orientation of reefs.
