The Spare Air Dial Gauge is one of the most popular accessory upgrade for the Spare Air system. It allows the diver to quickly see the cylinder pressure in increments of 200psi.

It is simple to install in any Spare Air cylinder. Just unscrew the pin style pressure indicator and screw in your new dial gauge. No special tools are required.

Please note that pony button gauges will not work with the Spare Air. This is the only authorised gauge guaranteed to work on the Spare Air.
