I have a hoyt mtsport and it has been a great and very consistent bow for the last 3 years. Well this year(summer/fall) it has become very picky about how you shoot it, it seems the vally has disappeared as well. I also noticed id get it drilling perfect shots and the next day would go out and would be hitting several inches to the right even though my form hasn't changed. when i looked at my site compared to the arrow and string it seems my sight has moved,But it hasn't been touched and i have marked the site to see if its moving for any reason and its not. What could be causing this problem? Could my cam be warped or something along that line? Anyhelp would be greatly appreciated as our season starts in 15 days and i need to get this solved or get a new bow. Thanks

It could be a ton of things. Take that sucker to a pro shop.

string stretch maybe, or if you are married and p.o ed your wife maybe she banged it around! If you cant figure it out yourself bring it in.
