specifications and have been brought together specifically for technical-level sidemount divers using a proven and widely adopted configuration.
The R2 TEC first stage regulator features a balanced diaphragm design with a dry chamber to environmentally seal the diaphragm and prevent freezing in cold conditions and also protect the working diaphragm in heavily silted water. These first stage regulators have 2 HP ports on either side of the 300 bar DIN fitting. A rotating end turret houses 4 LP ports around the circumference and a 5th LP axial port on the bottom end.
The rotating turret allows sidemount divers to store hoses neatly down the side of the cylinder and then deploy the full length of the hose when needed; for the short hose (left), this will be at the start of the dive (before or in-water).  For the long hose (right), this enables it to be neatly stored and then fully extended for gas sharing, or when it’s otherwise needed. The first stage is made from maritime brass with a high quality frosted chrome finish.
The 5th axial LP port comes installed in the R2 TEC1 Sidemount Regulator set. It is perfect for short hose connections to the BC and drysuit inflators, minimising clutter and improving the diver's streamlined profile. The first stage configuration also offers some movement for hoses routed down each side of a backmount BC wing when diving with regular twin sets. So while this is called a ‘sidemount set’, they’'re perfectly at home for backmount twin set diving, with a little swap of the hoses.
The TEC1 second stage regulator is a pneumatically balanced downstream regulator with both Venturi flow and breathing resistance adjustments. A heat exchanger improves operation in cold water by reducing the risk of icing.

- I stage R2 TEC x 2
