AREX ONE hides a micro-LED optical engine behind a transparent waveguide in the mask, so depth, dive time, gas mix, decompression status and compass float in your natural line of sight — no wrist check mid-dive. It is a standalone computer running the Buehlmann ZHL-16C algorithm, rated to 120 metres, with an RGB buddy light and a thumbwheel you can work in gloves. Optional modules add a wireless tank-pressure pod, a gaze-tracking torch and an AI marine-life identifier.
