Again as Jeff said the arrow in the bird helps keep i broke down so to speak. The main reason i crank mine down is because you sometimes have to hold for a long time and you dont want the i cant hold it any longer shakes to set in. Turkeys have awesome eyesight and can catch the slightest movements, so ill take all the advantage i can get. My bird last year camped out behind the decoy playing sumo with it for awhile after i was drawn before he went into attack mode then settling down and offering me a clean shot. I had to hold awhile at 63 lbs. I normally shoot deer at 68-70## pass through shots are deadly if exacuted right
