Complete system includes everything you need for 4 person setup. Very well cared for system that has been lightly used (2 systems never used). New, this system lists for about $1,625. Asking $800.
Includes:
(1) 22 Cu. Ft. Oxygen tank. Codes: DOT-3AL2216 BH0027742 M4002 09C06 CATALINA M22 2 TC-3ALM153 (due for recertification - about $50 at a Scuba shop)
(1) 4 Person regulator Model Precise Flight model 300-M
(1) Oxygen carrying case. Includes mounting straps to attach to seatback (worked great).
(4) A-5 Flow Meters (x4). These flow meters save oxygen controlling the flow for your altitude. Altitude reference markings engraved into the flowmeter with adjustable flow rate. I found them to be very good.
(4) Standard face masks (never used)
(4) Oxymizer Cannulas. These are designed to use less oxygen and work well with the A-5 flow meter.
Various fittings for compatibility with numerous systems
