The Oceanic Imperial Max Depth Double Gauge is a tough console SPG with both tank pressure and depth in a solid case. The bright white faces of each gauge are high contrast so you can read them at a glance and glow in the dark when charged with a torch.
The SPG has a linear scale to show how much pressure is left in your tank and the lower section has a water temperature gauge also.
Depth Gauge is non-linear with greater space between shallower depths, making the depth gauge more accurate the shallower you are, which makes shallow water stops easier to maintain and monitor.
