Oceanic Max Depth Swiv Combo Twin Gauges

The Oceanic Swivel Combo Gauges gives you a submersible pressure gauge for your air reading as well as depth gauge. The bright white faces make them easy to read underwater and glow under torchlight in the dark. 

The air pressure gauge is linear with a water temperature gauge at the bottom. The depth gauge is non-linear, with greater spacing in the lower depths, making it easier to maintain and monitor shallow depths for your safety stop.
