Product Information
This package pairs a Tusa regulator with the Tusa Safe Second SS-0001 octopus, giving you a matched primary and backup breathing setup in one order. Pick the regulator that fits how you dive: the Tusa RS-609U Compact Diaphragm Regulator, the Tusa RS1001, or the Tusa RS-790. The RS-609U uses a balanced diaphragm first stage for steady airflow and an efficient demand system for easy, natural breathing, and it is built with upgrades in mind, including an EK-600 cold water kit for temperatures below 50°F/10°C and a DIN-R600 conversion kit that extends compatibility to 300 bar/4350 psi cylinders.
The Safe Second SS-0001 rounds out the set as your backup air source. It has a compact, lightweight composite case and can be set up for left- or right-hand use, so it fits how you actually dive. A venturi adjustment lever gives you control over airflow to help reduce free-flow, and the ortho-consciously designed mouthpiece is shaped to cut down on jaw fatigue over a long dive.
Buying the regulator and octopus together means both pieces are on hand from day one, with no separate ordering or matching parts on your own. The SS-0001 is designed to pair with standard regulators, so however you configure your gear, air sharing stays straightforward.
