Wireless Transmitter — What It Is and Why It Matters
A wireless transmitter is a small, battery-powered device that threads into a high-pressure port on your regulator's first stage. It reads your tank pressure and sends the data via coded radio signals to your air-integrated dive computer, typically updating every few seconds.
Each transmitter is paired to a specific dive computer using a unique channel or code, which prevents interference from other divers' transmitters. Premium technical dive computers can pair with multiple transmitters simultaneously to monitor two or more tanks during gas-switching dives.
Frequently Asked Questions
How long does a wireless transmitter battery last?
Most transmitter batteries last 150 to 300 dives, depending on the model and dive frequency. Batteries are typically user-replaceable CR-type cells, though some models require dealer service.
Can I use any transmitter with any dive computer?
No. Transmitters are brand-specific and often model-specific. A Shearwater transmitter will not pair with a Suunto computer, for example. Always buy the transmitter designed for your computer.
