I have a tru-glo pedulum and it seems to work fine. On level ground it's simply a one pin sight and will shoot low at 30. From my balcony it shoots great unlocked. Good form will also help keep you on target. One suggestion practice on level ground with it unlocked. Mine gives off some vibration on the shot ( you can see it shake if I hold a long time and start getting the shakes) This vibration can throw your shot off especially if you use a shoot thru prong rest!
