#CO8400
Temporarily out of stock
The NiTek Q4 interfaces with your rebreather's O2 sensor and monitors the loop PO2. It comes fully unlocked with Full Trimix and Custom Gradient Factors with an optional Digital Compass. A hardware I/O port connects to the rebreather O2 sensor via a Fischer connector data cable, which is available separately.
Wrist-mounted, the NiTek Q4 is carries the tiniest of footprints, which is an added benefit for gear-laden rebreather divers. Better yet, the viewing screen takes up the entire footprint which means you get a large, easily readible display that is also dazzling bright, yellow OLED.

Intuitive, push button naviation allows you to focus on your rebreather and makes programming the NiTek Q4 a [continued]
breeze.
