Product Information
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.

Frequently Asked Questions
What is the Zeagle Compact Pony SPG used for?
It is a compact submersible pressure gauge for checking cylinder pressure on pony bottles, hang bottles and shop air tank systems. It reads in PSI and is intended for setups where a full size console gauge is not required, so you get a quick air check on a redundant or staged cylinder without adding bulk to your rig.
Does this gauge read in PSI or bar?
It reads in PSI. It is the Zeagle Compact Pony SPG PSI, part number 331-PG01-AA, so pressure is shown in pounds per square inch. If you dive with a team or on a system that references bar, keep that in mind when comparing readings between gauges.
Why choose a compact SPG instead of a full size gauge?
A compact SPG keeps hoses tidy and reduces clutter during a dive. On a pony bottle or hang bottle you only need a quick glance to confirm remaining air, so the smaller footprint keeps hoses tidy and suits setups where a full size gauge is not required.
Is the Compact Pony SPG corrosion resistant?
Yes. The gauge uses chromed brass construction for durability and corrosion resistance in wet environments. As with any scuba instrument, rinse it with fresh water after saltwater use and let it dry before storage to get the longest service life from the gauge.
