Thread: Things to look for in a range finder.

You can live without tbr, but angle can be useful either in the rangefinder or as northdude does. Simple rule of thumb for angles is 0-10° no change, 15° reduce measured distance 10%
35° reduce it by 20%
45° reduce it by 30%
Makes no difference if its up or down the same applies.
There are some excellent cheap rangefinders sold for golfers nowadays.
