RE: pendulem bowsights
No problem ! I used one when I first got started. I shot a Keller which was extremely noisy but worked!! Since then I have found that all the bows I have shot in the 250-300 fps range can easily shoot to 30 yrds with a 20 yrd pin out of a tree stand with very little or no compensation. You don't have to change anything when shooting on the ground and there are no moving parts to make noise with a fixed pin. I have seen some nice looking pedilums lately ,but I personally don't see any need for one unless your shooting around 200 fps.
