The Tek 3 Regulators have been designed to be used on twin cylinder set-ups. Utilizing dedicated right hand and left hand first stages, a diver can configure the Tek 3 regulators so that both external diaphragms face toward center and all hoses are able to route downward. This not only allows a more streamlined configuration, it is safer as it minimizes entanglement hazards in overhead environments. includes: a LH Tek 3 first stage, a RH Tek 3 first stage, 2 XTX50 second stages, a 2 meter hose, a 22" hose and a regulator necklace.
