The Ocean Reef high performance balanced diaphragm 1st-stage regulator is specifically designed for use with the Neptune Space Full Face Mask (see SKU's: OEDNSG, PCKNSG, OEDNSGK). The regulators use a diaphragm design to create an environmentally sealed mechanism to ensure durability and high performance even in contaminated water. The balanced diaphragm, chrome plated marine brass first stage regulator is inherently environmentally sealed. The benefit of this type of first stage design is that none of the delicate internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. 

CERTIFICATION EN250/2014 FOR COLD WATER

The MC9-SC/Compact Pro is designed to be used in cold water, making it versatile to be used anywhere on any trip.

It combines a balanced diaphragm 1st stage with a Sealed Chamber (SC) cold water system and a light and compact second stage, which offers high performance in water with temperatures below 10° C | 50 F.

This premiere travel regulator packs maximum performance into minimum space.

A true featherweight second stage, the Compact is built from lightweight techno-polymers to eliminate jaw fatigue.

Easy to pack and easy to dive, the Compact includes dive/pre-dive Venturi switch

for managing freeflow and maximizing performance at depth.
