Cessna1: I have the SkyGuard TWX Vision Pro with the 720 and after three flights I am 100% satisfied in all respects.  Great weather and traffic.  I have not talked with ATC yet to get a discreet squawk code to find out how well they see me and if all my data is coming through to them, but I plan to do that this weekend.  What has really amazed me is that I live in the middle of nowhere, but I can get FIS-B (weather) right in my living room, and I even have seen traffic leaving the pattern at an airport 3 miles away while I was sitting there in my living room.  I have made a few suggestions to Walter and Shane on the forum about tweaking some of the iFly ADSB features, but those are by no means show stoppers.  ====Ralph
