I just bought a Impact Archery Cosmic sight yesterday i put it on my bow and its dead on at 35 yds as low as the sight goes. My bow a Parker Hunter Mag set at 53lbs with 350gr Carbon Express Line Jammers. I also have some Carbon Express CX200' s that weight 311grs with a 75gr tip do you have any advice how to fix this problem?? I moved the sight up and down it either shoots over or is 5 inches high at 30yds. My bow isn' t shooting that fast so i don' t know what the problem is. Do you think by adjusting my rest would make a difference???

Look where you adjust your sight left and right . If you back those two allen head bolts all the way out you can adjust the height by pulling that plate off and replacing it in the proper holes for your set up ! Hope that helps !

I have the same sight and really like it.
Do not be afraid to play with it. You can take off the bracket the holds the sight and flip it over to gain more vertical adjustment. You can alsp take the whole thing apart, as I have done to get even more vertical by moving the pivot pin attached to the yardage adjustment arm. All in all, it is really just a matter of figuring out how much adjustment you need and re-arranging the pieces to give you that adjustment. It sounds harder than it really is.
