The 4000 PSI pressure gauge features a helical bourdon tube for a more accurate display of remaining air pressure. The depth gauge features a Maximum Depth Indicator for added safety and convenience. When used properly the Maximum Depth Indicator will read the deepest part of the dive, even if the diver is no longer at that depth. Precision engineered to the highest standards, and delivering quality that is second to none. An excellent choice for both beginning and experience divers.

Both gauges feature the Lumi-Nova luminous faces. TUSA is the first company in the world to incorporate Lumi-Nova light storage dials, a groundbreaking innovation offering several times the brightness of conventional dials, as well as longer luminescence times. The entire face glows bright enough to make it ideal for night diving or diving in dark areas but contains no radioactive materials.
