The 3000 psi, bottle gives a usable, completely redundant back-up supply of air that can be used by the diver with the system, or handed off completely to another diver if the situation requires it. RaZor valve/regulator. Envoy 2nd stage. Octo quick release. Mesh deploy bag. 

The pouch and bottle are positioned facing downward so that the drawstring opening of the pouch can be released allowing the bottle and regulator to be handed off to another diver while the pouch remains securely fastened to the BC.

Refilling the bottle is done with the supplied yoke transfiller which  allows the RaZor 1st stage to fill off of another standard yoke valve scuba cylinder.

This system is a grommet mounted system for BC vests without the capability of using the Zeagle Zip On System.

Pony Bottle System is easy to deploy and the safest backup in diving - redundant scuba.
