This OMS Pressure Gauge Stage measuring at 50mm is a very compact, lightweight, and perfect for stage / deco bottles or dive travel. The front lens is made of high density plastic surrounded by an overpressure relief o ring in case of over pressure. Comes with a double ended o ring air spool for swivel hose installation.

You can choose from a range of high pressure hose available in store, and we will fit it up for you.

What are Depth Gauges?

Depth Gauges are like the trip meter in our car, but are far more important. The purpose of the depth gauge is to tell the diver their maximum depth and current depth. These are important calculations in understanding the Nitrogen Tissue Loading discussed in our dive tables. Remember to use the dive tables effectively; we need to know our maximum depth and dive time. The timing device or watch is a critical component of this system. Because the dive table calculations are a hassle, many divers choose to use a diving computer to handle these calculations. I still recommend a backup depth gauge and watch, just incase the computer has a malfunction.

How does a depth gauge work?

Open Bourdon Tube Gauges contain a spiral shaped tube, much like the letter “C”. Water enters one end of the tube and as the pressure increases, the tube starts to straighten out. This straightening of the tube, in turns moves another lever, which moves the depth needle. Since the tube is open at one end, clogging can be a problem.
