The Hollis Pony Bottle pressure gauge
The dive tank finimeter Hollis Pony Bottle Manometer is a miniature pressure gauge from Hollis, similar to the well-known Oceanic Pony bottle Finimeter, a small and handy tank pressure manometer that was developed as a pressure gauge for decompression tanks and Pony Bottles.
In contrast to the surface tank pressure manometer such as the Polaris tank pressure gauge in our online dive shop, the Hollis Pony Bottle manometer is suitable for use underwater, while diving, and is connected to the high-pressure port of the regulator and not directly to the compressed air tank valve.
The display of the Hollis Pony Bottle Pressure Gauge is small but overseeable and can easily indicate a tank pressure of up to 300 bar with a 100 psi scale, clear and easy to read despite its small size.
The Hollis Pony Bottle pressure gauge can be connected to any standard high-pressure port and does not need a high-pressure hose, but is attached directly to the high-pressure port of the 1st stage and therefore makes sense as a tank finimeter for sidemount and spare tanks which you do not carry on your back.
The Hollis Mini pressure gauge for decompression tanks and spare dive tanks can alternatively also be used with Nitrox and even with 100% oxygen, which is very useful as it is used very often in technical diving.
You can of course also find other tank pressure manometers and pressure gauges for regulators in our online shop for diving equipment.
