Portable ADS-B for $849 from Stratus.

Having a device that tells me that there are nine targets out there without showing me where they are is totally useless.
It’s nothing but an expensive toy.
Five years ago, I had one that blue toothed to my iPad or iPhone both of which had Wings X on it. It was super fantastic. It showed all the taffic around me in real time on the iPad wings X map. It also had AHRS display and could get loads of extra info. I have to assume this one does as much. And I had all this good info while flying around in my '46 non electric Aeronca Chief. I considered it a very best buy. Hope this on can do as much for you.
