High-precision and high durability

The unique double diaphragm structure effectively prevent the accuracy decreases due to variations in temperature and atmospheric pressure. Also ,it is equipped with a friction pointer to help recording the maximum depth.

The zero point variation due to the atmospheric pressure change can be adjusted by the dial on the side. More accurate water depth can be indicated by performing the zero calibration before diving . Moreover, it is essential function for instance high-altitude diving.

Long-term stability of the accuracy

The diaphragm is the only moving parts exposed to seawater, which is double structured with the metal plate diaphragm covered by the rubble diaphragm outside. It prevents 100% the most common failures of the former water depth meters, such as the accuracy deteriorations due to the deposition of salt and corrosion of the diaphragm.

Tension automatic adjustment belt

The specially made list belt with a built-in spring adjustment mechanism in the buckle is supplied as standard accessories. It will prevent the phenomenon in which the fitting of the depth meter becomes loose as the result of diving suit shrink at wrist due to the water depth increase.

Luminous scale plate glows for hours

The scale plates of the depth gauge is painted with Japanese-made special phosphorescent agent, which will glow stably for hours once exposed to the light. It is ideal for night diving.
