Jeff, Thanks for all the good information. I have so little information on it so far, as the trip to Mark's was the first time I used it and there was no weather to see that day. I learned a lot by reading your post.
I think one significant thing to mention about the iFly720 is that it is really sunlight readable, which the IPad is anything but sunlight readable. My iFly had trouble acquiring the satellites when I first installed it in the panel, but now that I added the external antenna, it comes up with 13 satellites acquired almost immediately. Also, on the ADS-B reporting weather. The altitude you have to attain to get the signal is dependent on how close you are to a station. We have one about 40 miles away and get the light on at about 200 ft AGL. I also have the SkyRadar-L. The cost for that unit was around $600 and the iFly720 about $800. I have the iFly720 connected to my Dynon D-10A for the NMEA codes which gives me windspeed and direction. On the way back from Mark's I saw 56 MPH right quartering headwinds at times. I am now in the iFly beta program for release 7, so should have something to report on that soon, although I won't be using the portrait option since mine is mounted in the panel.
