The XS Scuba Navigation Console packs a pressure gauge, depth gauge and a compass module into a great ergonomically design console. This pressure gauge is a highly accurate bourdon tube design. The depth gauge is an air filled steel diaphragm gauge with a 0-200ft readout and maximum depth indicator needle (MDIN). This feature allows the diver to not record that depth while actually diving, yet will be available upon surfacing for later use for repetitive dive calculations. The red indicators are at depths beyond the standard sport limits of 130-200ft, warning the diver of the excessive depth. The Compass is liquid filled for a quick and responsive movement. A ratchet bezel with numerical compass headings in 30° Increments and 10° indicator markings for calculating compass headings.
