Heads up here is an AOPA guide below, and excellent news PRA is going to begin raffling a Trig T22 Mode S transponder with ADS-B out every month as long as we can break even. A lucky few will only have to pay $10 to upgrade.
Here is the link to the selection guide follow the flow chart as to where you fly and then click on the dark blue tap at the bottom with a white arrow to see the manufactures that are certified with the FAA: https://www.aopa.org/go-fly/aircraft...ads-b-selector
