This package puts two pieces of Tusa gear together so you’re not shopping separately for a regulator and a dive computer: the Tusa regulator and the Tusa DC Solar Link dive computer, one of each in every order. For the regulator, choose the RS-681, RS-790, or RS-609U to match how you dive.
The RS-681, the regulator featured in this bundle, pairs Tusa’s ultra-compact balanced diaphragm R-600 first stage with the S-81 second stage for smooth breathing in a small, low-profile case. It has 2 HP ports and 4 LP ports, a Venturi adjustment lever, and Breathing Resistance Adjustment Control so you can dial in the feel, along with a built-in moisture exchange plate and a MIFLEX hose for flexibility. Cold-water divers can add the EK-600 cold water kit for temperatures below 50°F/10°C, and the DIN-R600 conversion kit (300 bar/4350 psi) is available if you need a DIN fitting. It also qualifies for the TUSA CARE Free Parts for Life program in the USA.
The Tusa DC Solar Link dive computer runs on solar power, so there are no batteries to replace, and it uses Bluetooth SMART to send your dive log to a phone or tablet through the TUSA Diving LOG app. It handles 4 gas mixes from 21 to 100% oxygen, includes a Free-Dive Mode, and calculates ascents with the AA Buhlmann ZHL-16C algorithm, backed by audible and visual alarms and a backlit display with full-auto LED backlight for low light. Between the RS-681’s steady breathing performance and the Solar Link’s dive data on your wrist, this bundle covers the two things you check before every descent.
