- Wrist depth gauges.
- Highly accurate depth gauge can be recalibrated if unit is damaged.
- Maximum depth indicator.
- Sturdy velcro strap with stainless steel expanding buckle.
- Depth in meter (0-70m).
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.
