Product Information
This package pairs a Tusa regulator with the Tusa TC1 Wrist Scuba Diving Computer, putting the two pieces of gear you touch on every dive into one order. Pick your regulator from the Tusa RS-609U Compact Diaphragm Regulator, the RS1001, or the RS-790 to match the way you dive, then pair it with the TC1 for your dive planning and monitoring.
The RS-609U is built around a balanced diaphragm first stage that delivers steady airflow, backed by an efficient demand system for easy, natural breathing. It's set up for cold-water diving and future upgrades: the EK-600 cold water kit is available for temperatures below 50°F/10°C, and the DIN-R600 conversion kit expands compatibility to 300 bar/4350 psi cylinders.
The Tusa TC1 rounds out the package as a wrist computer for primary or back-up use, running Scuba, Plan, Free diving, and Gauge modes on the Buhlmann ZHL-16C algorithm. It's powered by a rechargeable Li-Ion battery, has an adjustable backlight, and gives you audio, visual, and vibration alerts to keep you aware underwater. The TC1 comes in Black or White and accepts an optional nylon strap (TA0906) if you want to swap the stock band.
