Some of the most important pieces of gear are submersible pressure gauges (or SPGs), which display the amount of air remaining in scuba cylinders. These can be mounted on hoses of varying lengths or, in situations where gauges are used with backup tanks, SPGs can be mounted directly on a regulator’s first stage.
Tank pressure gauges are useful tools in determining the pressure of a tank. And rather than relying on a regulator with a pressure gauge attached, small, handheld stand-alone submersible pressure gauges let divers more quickly see the amount of air left. These compact gauges fit easily in a scuba gear bag or save-a-dive kit. Most come standard with a DIN fitting, which can quickly andcontinue reading →
