Great condition, new in 2015 with about 300 hours of flawless operation. The Gemini makes a great IFR backup instrument, or VFR primary display for a budget panel. Weighs almost nothing.
Uses actual pitot & static inputs to give pressure altitude and indicated airspeed.
No wiring included, but none is included with new units direct from the factory either.
List price $1300, asking $800 shipped in the USA.
PM with questions or interest.
