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.
