Has anyone had trouble with a rangefinder giving crisp, confident, but incorrect readings?
I have an athlon 1 mile RF. I'm now pretty certain that it's off, but I want to cover my bases. I'm reading 550y on a target that was (by gps) around 620 and reading 760y on a target that was evidently 800-810. (Accidentally switching meters/yards and not noticing doesn't correctly account for the difference.)
For reference I'm using it on steel plates/chain/pipe assemblies completely surrounded by grass. No rocks, nothing else I could hit that would give clear, infinitely repeatable results.
for context: I had a crummy afternoon practicing yesterday, shooting miserably, consistently low. I was trying to practice acquiring, ranging, and hitting out at long range. Either 1) my RF is reading 40y closer than reality 2) my MV/BC are wildly incorrect (2 loads of 4 have been verified before, the other 2 were developed with choronograph this year.) It didn't occur to me to open Onx and measure until I got home, but I guess I don't quite know how accurate the straight-line measurement is. Probably very accurate, I just don't know.
Anyway, just wondering if anyone's experienced the same thing. I looked for quite a while but only saw a few posts about failing batteries from a long time ago. Almost all RF problem searches bring up no-reads or golf. Battery is the easy button but my gut tells me something else is going on. Trying to figure out something around town that has known distance in the meantime.
