The Novagrade Digiscope is expensive, but I can tell you I crushed it in my pack, dropped it countless times and dropped it while attached to the scope. Brush the dirt off and it was still set and locked in. The only issue was what others have said about the Athlon, the set screws on the eyepiece came loose from all the adding a removing the digiscope adapter. Did not effect the scope but the eyepiece would rotate under pressure. I have added red loctite to the set screws and tightened them back down. Other than that I am not sure why you would need anything better than this setup. It allowed be to field judge them from the pics on my phone, which made it that much easier of a decision on which ones were shooters.
