I notice on my phone's Kestrel app, that the "zero range" is shown as m(meters). so, when I send ballistic data to the kestrel itself, the zero range sets itself to 109 yds. I have not found a way to reset m to yds on the phone. I suppose that as long as I set the kestrel unit to the 100 yd zero, all should be good, but I don't like that they don't match. If I forgot to change 109 to 100 in the kestrel, wouldn't all my dope be off? Would all solutions be high? any suggestions please?
