The Pony Bottle Gauge is a tiny gauge that easily connects to the 1st Stage high-pressure port of any pony bottle or other alternate tank to show pressure in an easy-to-read display.
Any diver who has used a pony bottle knows the hassle involved with trying to find out how much air is in the tank. Switching regulators to view the primary pressure gauge or adding a separate pressure gauge to the pony bottle is a problem solution. Now with the Pony Bottle Gauge, all those headaches are over.
The Pony Bottle Gauge has a pressure range from 0 to 5,000 psi and is a great accessory for any dive bag.
