Product Information
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.
- Ultra-compact balanced diaphragm R-600 first stage paired with the S-81 second stage for smooth breathing (RS-681)
- 2 HP ports and 4 LP ports with a Venturi adjustment lever and Breathing Resistance Adjustment Control
- MIFLEX hose and S.E.A. Sequential Exhaust Assist technology on the RS-681 for flexibility and controlled exhaust
- Optional EK-600 cold water kit (below 50°F/10°C) and DIN-R600 conversion kit (300 bar/4350 psi) for the RS-681
- Solar Rechargeable DC Solar Link dive computer, no battery replacements needed
- Bluetooth SMART dive log transfer to the TUSA Diving LOG app
- 4 Gas Mixes (21-100%), Free-Dive Mode, and the AA Buhlmann ZHL-16C decompression algorithm
- Audible and visual alarms plus a backlit display with full-auto LED backlight for low-light visibility
- Choose your regulator at checkout, RS-681, RS-790, or RS-609U, and pair it with the same DC Solar Link computer
- One order covers both pieces of gear you check before a dive: regulator and dive computer

Frequently Asked Questions
What are the specs and features of the Tusa RS-681 regulator?
The RS-681 pairs TUSA's ultra-compact balanced diaphragm R-600 first stage with the S-81 second stage, giving 2 high-pressure ports and 4 low-pressure ports, a Venturi adjustment lever, and a breathing resistance adjustment control. It has a low-profile elliptical case, a built-in moisture exchange plate, and comes attached to a MIFLEX flexible hose. It also uses TUSA's S.E.A. (Sequential Exhaust Assist) exhaust design and an ortho-consciously designed mouthpiece.
Is the Tusa RS-681 available in DIN, and does it work in cold water?
As sold, the RS-681 is a standard (non-DIN) regulator, but TUSA offers an optional DIN-R600 conversion kit rated to 300 bar/4350 psi if you need DIN. For cold water below 50°F/10°C, there's also an optional EK-600 cold water kit. Both are separate accessory kits, not included as-standard on this regulator.
How does the solar charging work on the Tusa DC Solar Link dive computer?
The DC Solar Link is solar rechargeable using sunlight or indoor fluorescent light, so there's no battery to replace. Our data doesn't include specific charge times or runtime figures, so we can't quote numbers on that.
Does the DC Solar Link dive computer sync to a phone, and what gas mixes does it support?
Yes, it transfers dive logs to a smartphone or tablet over Bluetooth SMART using the TUSA Diving LOG app. It supports 4 gas mixes from 21-100% oxygen, plus Scuba, Free-Dive, and Altitude Smart modes, and uses the Buhlmann ZHL-16C algorithm for decompression guidance.
What's included in this Tusa regulator and dive computer bundle?
This bundle includes one Tusa RS-681 Regulator (1st and 2nd stage set) and one Tusa DC Solar Link Dive Computer (IQ-1204), one of each.
