Enjoy the convenience of air integration without the hassle of a dangling hose. The low-profile transmitter screws into a high pressure port on your first stage and relays tank pressure and true remaining bottom time (RBT) to the computer screen. Featuring a more visible built-in LED on top of the cap, it provides an estimate of tank pressure when the first stage is attached to a tank letting you know if the tank has gas without needing to activate the computer.

• Easy to use, you only need to pair it to your computer once - the first time you use it
• Coded transmission technology prevents interference between different dive computers
• Compact size improves first stage mounting options
• More visible LED indicator status light: 1450 PSI and over = Slow Short Blinking Green Light; Between 1450 PSI and 725 PSI = Short Double Blinking Yellow Light; Below 725 PSI = Long Single Blink Red Light
• Powered by a user-replaceable CR-2PE/BN lithium battery that's good for three years or 250 to 300 hours of diving, whichever comes first
