If you get a lighter disc so the weight plus AirTag still turns out the same, it apparently doesn't affect flight. As long as it’s centered of course; not hard to do if you mark where it’ll go ahead of time.Wouldn’t having an Airtag attached to the disc cause all sorts of problems with your throws?
I’m sure for people who are actually good they’d be able to tell, but I can’t, and those people won’t need a tracker anyway. For me, as long as I don’t hit too many trees, it’s great. Can just throw and know I’ll be able to find it. A real relief, actually.
