Aqualung Transmitter – Wireless Air Integration for Dive Computers
Upgrade your dive setup with the Aqualung Transmitter, designed to provide wireless tank pressure information directly to a compatible Aqualung dive computer. By eliminating the need for a traditional high-pressure gauge hose, it helps create a cleaner, more streamlined configuration while keeping important gas information easy to monitor throughout your dive.
When paired with a compatible computer, the transmitter sends current cylinder pressure and supports calculation of gas time remaining, giving you quick access to essential dive information from your wrist.
Once paired, the transmitter remains linked to your dive computer, helping prevent accidental connection with another diver’s computer. It also uses a commercially available, user-replaceable battery, making ongoing maintenance simple.
Compatible with Nitrox mixtures up to 40% oxygen, the Aqualung Transmitter is an excellent addition for recreational divers wanting convenient wireless air integration.

How the Features Help
- Wireless pressure data: The transmitter measures cylinder pressure and sends it to a compatible computer, keeping the information close to the rest of your dive display. Correct pairing, gas assignment and installation are part of the setup.
Compatibility and Use
Match the exact instrument model, generation, part number and attachment arrangement before ordering. Listed compatibility applies to the identified accessory, not every product from the same brand. Check the supplied items and follow the instrument’s installation or service procedure.
Gear Care and Maintenance
Rinse the exterior gently with fresh water after diving and dry completely before storage. Protect the housing and first-stage connection from impacts; do not lift or carry a cylinder by the transmitter.
Have installation completed with the fitting, flow restrictor and gas-compatible seals specified for the exact transmitter. Depressurise the system completely before removing the transmitter or opening a user-serviceable battery compartment.
Use only the battery, seals, tools and lubricant permitted by the model manual. Keep oxygen-clean equipment free from incompatible oils and grease. After service, check for leaks, confirm pairing and verify the correct gas assignment and pressure reading before diving.
