Up for sale is a vintage Voit Avalon III Two Stage Regulator. The first stage reduces high pressure air from the cylinder and the second stage further reduces that air to match the water pressure for easier breathing. Included is the regulator, chin rest (strap is missing), hose and valve. 

This is intended for display only and is no longer suitable for modern diving. The chin rest is dry rotted and cracked and all pieces have signs of age and moderate usage.

Thanks for looking and happy buying!
