How we calculate scores →About this gear
OXY S3NS0R is a compact display for one analogue galvanic oxygen sensor in a rebreather system. Its always-lit OLED and simple control arrangement focus on reading that sensor rather than providing a complete dive computer.
Consider before buying
The cable is permanently attached and not user-swappable. It uses a 3.6 V 1/2 AA 14250 lithium battery, with up to 75 hours stated operation. One display reads one sensor; the manufacturer supplies a mounting plate with an order of three units.
Our take
Choose it when the approved monitoring arrangement calls for a simple galvanic-sensor display. It is not a direct substitute for a multi-sensor controller, and the digital DiveO2 sensor should not be assumed to connect to its analogue input. Confirm the full rebreather integration before ordering.
