The Spare Air 600PK-NDG Package – Nitrox with Dial Gauge is a compact emergency air system for scuba diving. The 6.0 cu ft / 170 liters cylinder provides more air than the standard 3.0 cu ft Spare Air, supporting surface breaths during an ascent in an emergency. Designed with Nitrox divers in mind, it remains small and light enough to hardly notice while worn, yet dependable when you need it. The aluminum cylinder is black anodized and fed by a balanced single-stage regulator with a dial gauge for easy monitoring.

The package includes Spare Air, Holster, Safety Leash, and Refill Adapter. It can be refilled quickly from any full SCUBA tank, making it a practical addition to your scuba gear kit. Weighing under 4 lbs, it is one of the lightest emergency air systems available for divers.
