This TUSA regulator set pairs three components built to work as one system: the RS-681 regulator, the SS-0001 Safe Second octopus, and the SC-0301 three-gauge console. The RS-681 combines an ultra-compact balanced diaphragm R-600 first stage with the S-81 second stage, giving you 2 HP and 4 LP ports for mounting your other gear, a Venturi adjustment lever, and a Breathing Resistance Adjustment Control so you can fine-tune airflow to your liking. A MIFLEX hose adds flexibility on the primary second stage, and the RS-681 is eligible for the TUSA CARE Free Parts for Life Program in the USA.
The SS-0001 octopus backs up that primary regulator with a lightweight composite case that switches between left- or right-hand configuration, so you can set it up the way that’s comfortable for you. It uses the same style of Venturi adjustment lever as the RS-681 and an ortho-consciously designed mouthpiece for comfortable, easy breathing on longer dives, all in a high-visibility yellow case that’s easy to spot underwater.
Rounding out the set, the SC-0301 gauge console keeps your pressure, depth, and direction readings in one place. It reads air pressure with a 500 psi reserve marking, shows depth in feet, and includes a Northern Hemisphere-balanced compass, so you can plan and track a dive without adding separate instruments to your rig.
