I flew to Huntsville, TX today and noticed that they have a JPI 450 Fuel Scan and transducer for sale. The sign says it only has 24 hours/one year of use... $350.00.
Call Huntsville Aviation, (936)295-8136. I think it's a decent deal for a very useful piece of safety equipment.
It was installed in a Swift by HA, then removed at the next annual to be replaced with a Garmin G5. The owner of the FBO, Wade Gillespie, did the install.
