The Air Buddy Set mounted on a regulator 1st stage.
The Pony Set consists of two standard parts and one optional:
1. The Air Buddy itself
2. The Safety valve which will protect the diver from a malfunctioning 1st stage preventing the low pressure to rise above 190 psi.
3. The optional mini-pressure gauge which allows the diver to read tank pressure at a glance. Sea Turtle Scuba offers these gaugauges as an accessory.
To rig a pony bottle your size.
The basic set includes the Air Buddy,
the mounting swivel and the safety valve, shown below.
The Air Buddy allows the diver to put together a pony bottle rig that provides enough air to get back safely from whatever dive is planned.
The photo at the right shows the Air Buddy Pony Set being used on a 6 cubic foot pony bottle which is small enough to put in your BCD pocket and carries enough air to get back safely and comfortably from any sport diving depth.
You can just as easily put it on a 13 cubic foot or larger pony bottle.
If you want to use it on a large pony bottle that would be fastened to your main tank, you can use the Air Buddy rigged with the low pressure octopus hose to reach around to the front.
The picture on the left shows you the Air Buddy mounted on a specially designed tank valve that includes a regulator 1st stage within its body, making a more convenient device.
