Many divers take compasses for granted, considering them just an accessory to an overall dive gauge console system. Trying to navigate with a poorly designed or improperly functioning compass can be one of diving's more frustrating events. The XS Scuba Standard Compass is liquid filled for a quick and responsive movement. A ratchet bezel with numerical compass headings in 30 Degree increments and 10 Degree indicator markings for calculating compass headings. Bezel has heading indicators for alignment of compass course and a lubber line across the compass face. A side window with compass degrees allows gun-sight accurate use when precise headings are required. Compass card is luminescent for low light or night diving conditions.
