Need a rangefinder. What are the top three at any price and what are the top three for the money. Weight is an issue (will be carried in fanny pack) and this not for shooting past 1000 yards (I'm in NC and 90 percent of time will be used to check between 250 and 500 yards), but would not mind having capability to go longer for infrequent trips out West or resale if I end up never using it . Are they all accurate? Can any go to 1000 yards and still be used for bowhunting 20-40 yards or is that not possible?
