The XS Scuba's Wrist Depth Gauge is an air-filled steel diaphragm depth gauge with a 0' to 200' readout and maximum depth indicator. The maximum depth indicator needle (MDIN) is pushed by the gauge depth needle until the diver meets their maximum depth. The MDNI will remain at the maximum depth reached for the duration of the dive to indicate the diver's deepest depth reached during the dive. This feature allows the diver to not record that depth while diving, yet will be available upon surfacing for later calculations for repetitive dives.

The colored graphics of the gauge face allow quick glance monitoring with bright red depth indicators at strategic positions on the gauge face. The red indicators are at depths beyond the standard sport limits of 130' to 200'. Gauge face is luminescent for low light and night diving situations. Gauge measures (diameter base) 2.41", (diameter top) 2.18", (depth): 1.13" (6.12cm x 5.54cm x 2.87cm).
