RE: Do you use a Rangefinder?
As others said, it's an ESSENTIAL piece of equipment for me as well. I'll rarely leave home without one if I'm hunting. A lot of shooting as well as ranging enables you to be able to know exactly how to hold for that shot that you just ranged at 35.5yds when you havea 30 and 40yd pin, and you want to hit a 3" target.
