Zaon MRX collision avoidance

New lower price! "This unit incorporates fourth-generation PCAS technology in a compact feature-filled unit. PCAS, or Portable Collision Avoidance System, is the technology developed exclusively by Zaon Flight Systems that makes this unit possible." I purchased the unit in 2007, used it for 5 years in my ASH 26 E, but it became redundant when I installed Powerflarm in the glider. I really liked the MRX, so I held on to it, but now I want someone to benefit from it, instead of sitting on my shelf. The unit (sn 23011) worked properly in flight about two months ago, detecting all transponder-equipped targets that the ADSB unit reported.
