Since my range finder measures line of sight and doesn't adjust for effective ballistic range at the horizontal, I need a way to convert in the field.
My estimates of the cosine values are .966 at 15 degrees, .866 at 30 degrees, .71 at 45 degrees and .5 at 60 degrees.
I hunt in the mountains so need a wide range.
Is there an easier way to do this?
Thanks in advance.
