Ok Don,,but the Rawson controller can be run manually, with radar, or GPS,the latter two choices are optional.I was just thinking if I could us my itc receiver I would not need the garmin. I have not even priced the garmin,but it probably is not all that expensive.

There are probably times when radar would be the best choice,for instance working next to tall tree lines.I already have radar so it could be used as a backup if I wanted.
