The Aqualung i450T Dive Computer has 4 modes Air, Nitrox, Gague and Freedive. With a freedive calculator the i450T allows you to switch between Freedive and Dive on the same day. The i450T also features a digital compass featuring a North reference and bearing lock.

 The Aqualung transmitter, an optional extra, provides the paired computer with Aqualungs patented Gas Time Remaining Algorithm allowing accurate gas management in real time. The i450T and i750T are compatible with up to 3 different transmitters and gas mixes on a single dive.

The i450 is compatible with the optional PC / MAC interface cable that allows dive data to be transferred to your computer using the Diverlogsoftware. It also allows you to update the dive computer firmware, eliminating the need to return the dive computer to a dealer if an important update becomes available.
