The Appareo Stratus 2i is an ADSB-in unit that's intended for use with the Appareo ES or ESG ADSB-out transponder. Unlike stand-alone units it has no internal battery or antenna, and probably can't practically be used without the Appareo ADSB-out unit. Its output is in a format usable only by ForeFlight and not by other similar apps.

I have a Stratus 2i that's worked flawlessly for many years which I recently removed to replace by a 3i that can work with other apps. I think the 2i would be useful only in an Appareo system that doesn't currently have a working one. Please send me a PM if interested in it.
