With the Suunto Wireless tank pressure transmitter you can monitor tank pressure and air consumption data at the same time as you monitor depth and time – directly from your wrist. The transmitter also enables your compatible dive computer to show an estimation of the remaining air time throughout your dive. Real-time air consumption is also stored in the computer’s memory so you can track your consumption from dive to dive. The pressure readings from the transmitter are displayed both numerically and graphically on your dive computer.

The transmitter is powered by a user-replaceable 3v lithium ½ AA battery. Replacement battery kits also contain a new O-ring and cover, which must be changed at the same time. Battery life is around 2 years (at 100 dives per year).
