This listing is for a Aqualung Titan LX Scuba Regulator System. Included is a Zoop computer  with PSI gauge. Also included is an Aqualung Octopus and bcd inflator hose.  It appears to be working as intended by the manufacturer and looks to be in pretty good shape. 

Like all dive gear it should be checked but a professional, who is authorized by its manufacturer, prior to using it to support life underwater.
