Dive gear maintenance: Gauges

The depth gauge is most often prone to sand build up on the sensor. Scubapro are really bad for this because the sensor is covered by a flimsy sticker, which lasts all of about 10 dives, and the gauge will often show 3-4 metres’ depth out of the water.

Remove the gauge from its rubber holder and rinse the sand off around the sensor and in the molded rubber housing. Avoid pressure on the sensor as it is extremely sensitive.

The source of many minor leaks is often the swivel pin. These seals will be changed when your gear is serviced.

Not everyone will agree with this but I take a sponge with liquid silicone on it and wipe my hoses, regulators, and gauges. I leave it on for a minute or so and wipe it again with a clean dry cloth. I also wipe the thread of the A-clamp screw or yoke threads with the silicone sponge. I find this prevents corrosion and salt build up on the gear and I have a Mares regulator with well over 1000 dives that looks and works well.
