The Zeagle Compact Pony SPG PSI is a compact submersible pressure gauge designed for scuba and diving applications where a full-size gauge isn’t required. Its small footprint keeps hoses tidy and makes quick air-read checks on pony bottles or hang bottles convenient, avoiding the clutter of longer hoses during a dive.

Built for reliability in wet environments, this gauge uses chromed brass construction for durability and corrosion resistance. It integrates smoothly with pony bottle systems and shop air tank setups, delivering a clear PSI readout to help manage remaining air during gear configurations and diving operations.
