Balanced dry chamber membrane system for cold water

Without turret

4 3/8'' UNF MP outputs

1 outlet 7/16'' UNF HP

Four low pressure ports all mounted on a rotating turret. This results in optimal routing of the whip eliminating its possible sharp bends.

Designed for divers seeking reliable performance and simplicity, the diaphragm-balanced MK11 regulator, with its specially designed chrome-plated brass body to reduce size and weight, is an ideal travel companion.

The new MK17 EVO is an entirely watertight system, ensuring trouble-free operation regardless of how cold or cloudy the water becomes. Although it is more compact, it provides better breathing performance than its predecessor.
