HI Everybody i just bought a used mathews drenalin bow it is all set up with sights and everything draw lenghth is right for me at 29 inches but i was wondering does peep sight half to be re set for each individual that uses the bow or can it be left alone.

Depends mostly on wether your anchor and the previous owners anchor are close enough for the peep to line up for you. Draw and anchor. If you've got a good sight picture thru the peep get about 10yds from the target and give it a try. If not raise or lower the peep until you can see thru it.
Almost forgot! GOOD bow!

til later

Close your eyes, draw your bow and anchor. Open your eyes and where are you? You need to move the peep sight so it's directly in front of your eye. You shouldn't have to stretch or move your head around. With the peep set at eye height, you'll have a better chance of developing a good, repeatable, natural shooting form.
