OTG Scuba Diving Underwater Wrist Compass Gauge is a robust and accurate compass for underwater navigation that ensures accuracy and durability for a long time. This compass comes with a wrist strap fitted so that divers can use it as a wrist compass. It is also supplied with a BCD hose holder. Thus divers can remove the wrist strap, fit the compass onto its BCD hose holder and safely attach the compass onto the BCD inflator hose. The magnetic plate moves extensively in all direction, so that reading is accurate even if the instrument is not held perfectly flat level. The compass face is luminous and divided into 10° intervals. Reading can take place by looking at the instrument from above, or more easily, through a special reading window that enables more precise tracking of the compass. On the top there is a red line. A swivel trigger lunette with a double pointer means the direction can be memorized.

(Please note that our compass is for Northern Hemisphere.)
