Make sure it’s optioned with the GPS and if not purchased with an encoder, check to make sure that it’s compatible with your existing encoder.
You’ll be up for a mounting tray and some wiring here and there, plus fitting and certification.
I would expect to walk away after forking out $7.5-$8k. IF your application is approved, the 50% off would be handy.
You may not need it however the base unit isn’t certified for IFR. You’ll need to spend thousands more to appear on the ATC screen like IFR aircraft. My understanding is that you will appear in a different colour/icon as you’d be uncertified.
If you’re in a metro area primarily, the ATC folk won’t see your ADSB as primary and will see your mode S, so in some ways it feels more cost effective to buy a SkyEcho as it gives you ADSB-IN as well for only $900 !
