$450, buyer to pay shipping. The SK 12-24 Twenty Four Cubic Foot complete oxygen system is easy to refill with aviation-grade breathing oxygen (MIL-027210, Type 1). Includes a pressurized cylinder with 4 oxymizer cannulas, lines, a flow indicator, quick disconnects and padded carrying case. Also I'm including FlightStat Digital Fingertip Pulse Oximeter used to check in-flight hypoxia by monitoring your oxygen saturation and pulse rate with the FlightStat Pulse Oximeter. FlightStat is the original aviation-specific pulse oximeter and does not require a prescription! All items are in excellent condition (used only a couple times) and I can supply photos if needed.
