Quite often in the shadows of the woods, distances can be a little decieveing. Last yr. I shot at a doe I thought was around 25-30yds. Turned out she was 40yd. Put the arrow right at her feet. Where I hunt is heavy pine, & it's a little darker in there, vs an open hardwoods area. This yr I bought one to range out a bunch of trees to have a better knowledge of distance. Also, use it for out west.
