The OMS Compass is a liquid-filled compass with a phosphorescent compass card and a large side reading window. The ribbing on the bezel offers a secure grip, with easy-to-read high contrast numbers in white with a ratchet at every fifth degree. The OMS compass includes a low profile depth compensating bungee mount plus the bungee (aka shock cord). This version is balanced for the Northern Hemisphere only. OMS logo is on the compass card in the "South" location.
