I'm new to bowhunting and when I purchased and got fitted for my new bow, the salesman recommended that I get a sight with only one sight on it. Now that I'm adjusting to the bow, I think I would like a 3 sight instead of one.What do you recommend for a beginner? To me a 3 sight that's sighted in at different yardage, would eliminate the guess work. Or at least would make it easier. Please Help!!!!!
