This is the Pulse-On-Demand oxygen system used by paraglider and hang glider pilots. This kit comes with the AL-113 or AL-180 aluminum oxygen cylinder with a Holster Pack (tank protector bag), the XCR primary reducing regulator, low-pressure service line, and the EDS (electronic delivery system) unit and breathing cannula. The low-pressure service line is a high quality polyurethane line that is kink-resistant and flexible under varying temperatures. The cannula and service line connect to the EDS unit via color-coded "Quick-Connects" providing an air-tight fitting by hand. These fittings can be connected and disconnected many times.
The unit is very easy to use, and the instructions are well written. You can set your unit to begin releasing oxygen at a desired altitude. The EDS system senses the pressure change when you inhale, and releases a calibrated dose of O2, depending on your altitude, making for a very efficient system. You will stay warm at altitude and make better decisions during your flights with a good oxygen supply.
