RE: setting 20 yard pin and shooting under 20
i love bowhunting, and yes, your first pin should be able to suffice from 0-20 or 25 yards. if he sighted it in, his 20 yards arent going to be your 20 yards. you have to sight in you bow to you. when adjusting your sight, chase your arrow. if the arrow shoots low, move your pin lower. if the arrow shoots left, move your sight left.
