The Aqua Lung i300 Dive Computer is an easy to use, rugged dive computer that supports a nitrox mix up to 50% oxygen, four diving modes, audible alarms that are reinforced with a high visibility LED warning light, easy two button navigation and a choice of colours.

The i300 uses an easy to read segment style display which provides large, clear digits. A graphical ascent rate meter is shown on the left and a deco load indicator on the right for quick glances whilst diving. The backlight provides plenty of illumination when light levels and visibility are low.

The i300 can be connected to a PC or MAC using the optional interface cable that allows your dive data to be transferred to the Diverlog software.
