Hopefully some one can help me. I tried to sight in my new Matrix but I have adjusted the sight all the way in and it still shoots about six inches to one foot to the right. I attempted to adjust my rest to try and make up for the lack of adjustment in the sight, but I had to adjust the rest out so far that the arrows started fishtailing. Any suggestions?

Are you torquing the bow?

you could, or probably is your form. try working on that see if it helps

Sounds like you need to seek the help of your local pro shop.. and have them make sure that you have everything setup correctly. The rest should be set for center shot w/ the proper nocking height. Have you done any tuning to verify that the arrow is even flying correctly out of your bow? Or did you just pull your bow out of the closet for this week for next weeks bow season?

Im fairly new to bowhunting but have the same sight and setup mine by myself with lots of research and reading on this website. 1st make sure your pins are lined up with your arrow.
With my dom. eye look down the string as if shooting without drawing bow back and line up
sting, arrow, and sight pins(it should put you in the ballpark. Then I start out @ approx. 10 yards, shoot and keep moving back and adjusting vertically until your hitting close. Then you can micro adjust pins. Once 20 pin is set my other pins fell right in. Mark your placement with whiteout/tape on vertical/horizontal adjustment after getting groups like you want just in case they get bumped out of place(I learned this the hard way)Hope this helps.

I discovered the source of my sighting problem. I contacted Trophy Ridge and explained my problem. It appears that bow designs have changed approximately 2 years ago, my bow is 6 years old. The riser design on new bows is different. Trophy Ridge designed their sights for the new bows. They are sending me a spacer to place between the riser and the sight to compensate for the lack of adjustment. Problem solved. Thanks.
