Aqua Lung's Transmitters, used in conjunction with a compatible wrist computer, allow you to monitor current pressure and gas time remaining.

This is the same transmitter used by Shearwater and Oceanic.

Once paired with the computer using the transmitter unique serial number, the transmitter is permanently paired and will not accidentally pair with other computers.

Unlike the transmitters produced by many other manufacturers, the battery is user changeable and commercially available.

How to change the Aqualung Transmitter battery

This tank pressure wireless transmitter (OEM by Pelagic Pressure Systems = FCC ID MH8A), is compatible only with those specific models of Shearwater Research, Aqualung Hollis, Oceanic, and Aeris brand dive computers that support hoseless air integration. 

The transmitter is rated for depth up to 150 m.

Uses a user replaceable, widely available, CR2 photo battery.

Some divers prefer to use a short 6-inch HP hose to reduce the risk of the transmitter being mistaken as a handle to lift with.   Do not forget to order the required HP Swivel Pin.

The High Pressure o-ring located at the base of the transmitter is Size AS568-012, Viton™ material while the battery cap o-ring used is Size AS568-016, Nitrile (Buna-N) A70
