    Hey fellas,

    So i have been sighting in my new bow and everything has been going pretty well. I had it all sighted in at 20yds and everthing is well (i even robin hooded an arrow..oops). Anyway, so my issue is now that im good at 20 i went out to 30 and 40. It seems that once i pass 20 yrds my arrows keep hitting to the right almost every shot (about 3-5inches). I feel that i have pretty good form and release but im still working on it. What could cause these issues? I don't want to move the sight b/c it would mess up my 20 yrd. Could the rest be out of line just a bit?

    The rest needs to come left , get it shooting good at 30 then check it at 20 then jump back to 40 and see whats up .......make sure you dont have or get any fletching contact and make sure your not torqeing your bow , keep your grip loose , after you get it close your center shot that is then fiddle with your sight .

    sit your bow on the floor on your bottom cam holding it up by the top cam or ideler wheel with an arrow nocked and see which way your arrow is running out of your bow , one way i set my center shot is i attach a piece of thread to the center of my top limb bolt with tape and pull it tight to the center of my bottom limb bolt , then i losen my rest with an arrow in it and move it till my arrow touches the thread then i lock it up ........just a tid bit of info i thought i'd pass on.........providing you dont have any cam lean .

    I just moved the rest to the left just a tiny bit and i am now right on the money. Thanks for the help. The dealer set up my bow and used a laser and everything to make sure it was straight but i guess it was slightly off. I guess the further out you shoot the more any imperfections surface.

    A piece of thread done like i mentioned will walk all over a $125.00 or more bow lazer for an initional bench set up , that right there is a proven fact .

    Sorry, but that is not "fact". Any tool, used incorrectly, can do a bad job. Besides, the laser could have set centershot and he had weak spined arrows which would have caused the reaction he had. Moving the rest off of centershot would compensate for the weak spine. He could have lowered the draw weight and fixed the problem too and still been on centershot.

    Centershot is centershot, the power path of the string. You can find it with a string, a laser, a rubber band, but, once you set centershot, when you start moving the rest, you are moving off of centershot.

    :violin: Just for the sake of argument, what is the draw weight of your bow, and also if you can tell us off hand what the spine on your arrows are. As every one has already stated your problem could either be that your bow is a bit out of “Tune” or you may be a bit underpinned.

    Google how to do a "walk back" tune. (not hard at all) once you get your rest adjusted correctly , you can start adjusting your sight. I promise , walk back tuning a rest is the best thing since sliced bread.

    No it didn't. The laser set centershot and then the rest had to be adjusted because of a weak spine. Like I said earlier the DW could have been turned down to accomplish the same thing and then the rest would still be at centershot. As it is, the rest is no longer at centershot.

    How do you know the spine isn't correct and the guy using the lazer set the rest due to cam lean ....?

    I agree with Bruce. I would've started with lower the draw weight personally. If the shop used a laser to set centershot, I'd prefer to leave the rest alone instead of compensating for a weak spine.

    If you were to use the laser to set the rest to something other than centershot then you are using it incorrectly. I have checked cam lean with a laser but there is no reason to set the rest to something other than centershot unless you do not know what you are doing.

    Thanks, but you are still compensating for a weak spine by lowering draw weight. The reason I believe adjusting something other than the rest is more effective than moving the rest off of centershot is because at centershot the bow performs most efficiently. That was the way it was engineered. Now, moving the rest off of centershot will still produce a killing arrow but that is just not my preference. IMO, there are better ways to get tuned without moving the rest.

    Hey Italian take your bow to a reputable shop and have them set your bow up properly.
    I personally would never let anyone use a laser or a sting on my bow.
    It needs to be set up according to YOUR bows center flight.
    After you have your bow realigned simply do a walk back shot.
    Start at 20 using your 20 pin then walk back to 30 and 40 still using your 20 pin and aiming at the same spot as you did for your first shot. doing this will help you see if your windage is good and or if you are torquing your bow.
    You do need to make sure you are shooting the correct spine for your draw wght but that should not make you shot left consistantly usually the arrows deflection from the shot is an up and down movement not a left to right.
    Good luck.

    Please remeber once your rest is set for center flight of YOUR bow and level leave it alone.

    I understand completly where your coming from I do the same as well .....I tune my broadheads as well with the poundage ....
    but without seeing this guys bow that's why in my first or second post I had asked him to check the direction of the arrow coming out of his bow....its possible the guy really didn't have it set correct

    If the bow model is the same centershot is not different on each bow. In fact, centershot is the same across a number of models also. There is no magic to finding centershot, heck, you can use a ruler to find it. Lasers, strings, rubber bands, rulers, eyeballing, etc. are all valid methods of setting centershot if you know what centerhsot is and have a little experience.

    I agree, but the incorrect setting would not be due to using a laser, it would be due to the lack of ability by the guy using the laser.

    I took this to imply that a string is better than a laser. The bow shop guy can misuse a string, or any other method, also.
