I have a mathews Z7 (ok I know what all the hoyt shooters will say) and I have alligned the arrow straight at centre , but in order to hit the target my sight has to be app. 3 mm to the left of the centre . Is that because the cables run to the right or can I do something to allign the sight to the centre . Now I basically would have to aim a fair bit to the right of the target if my sight was in line with string and the tip of the arrow. I hope that you can understand what I mean.
