I bow hunt almost always even during gun season, I have no need to waste money on a range finder because know my area.when I set my stand and cut my lanes I use a rope tied to my stand that's marked and measure 20 ,30 ,40 yards and poured corn in an arch or half circle and also to this bush or other points so now when I see a deer I can tell you how far it is because I know my area . Cheaper and most importantly when he comes your lucky to have time for a shot ,if your forced to use a range finder your wasting valuable time and risking the chance of your prize walking away
