Experience the convenience of air integration without the hassle of a dangling hose. This low-profile Smart transmitter seamlessly connects with SCUBAPRO's advanced dive computers. It securely attaches to your first stage's high pressure port and transmits tank pressure and true remaining bottom time (RBT) to the computer screen. The latest version includes a built-in LED at the top of the cap, providing an estimate of pressure when the first stage is connected to a tank. Stay informed about your tank's gas level without the need to activate the computer.
