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.
The T10-SEAL CHAMBER 1ST stage is environmentally sealed, protecting it against icing in cold water and against contamination from particulate matter in silty conditions. When paired with the Master second stage, which includes an internal heat exchanger, this regulator is an excellent choice for divers exploring the most extreme cold water environments.
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.
