The Digi 2 is a digital pressure gauge and bottom timer with additional features. It is equipped with a user-changeable battery that can last for 700 dives over a year. 

The device features a luminescent display that shows the current tank pressure, temperature, dive time, current depth, and maximum depth. 

It also alerts the diver about the remaining time they can spend at the current depth before the pressure in the cylinder drops to 50 bar. Its depth range is 0-120 meters.
