Hollis 221 DC-3 Regulator

Built with the same quality as the DC1- without the swivel turret- the Hollis DC3 is the ideal 1st stage for double cylinder configuration as well as perfect for single cylinders.

Paired with the 221 Second Stage which uses the same technology as the 212 without the dynamic adjustment  -this reg set is designed for those who believe keeping it simple is the best way to go.

Easy breathing, light weight configuration, which significantly reduces jaw fatigue compared to many other regulators -has earned its loyal fans.
