Sometimes a standard submersible pressure gauge with its large dial, extra weight and long hose is too much for the job. If you want to get a quick idea of how much air is in a cylinder and you do not want to deal with the tangle that longer hoses can present, then a Zeagle Pony Gauge is the answer. Perfect for pony bottles, hang bottles, and even a tank/regulator used for shop air.
