Sight Pin
 

HI,
I'm a newbie to the sport and left handed. My sight pin is not lined up with the centre of my arrow rest, its about a 1/2 inch to the right. Is this wrong, if I'm still hitting the Bullseye at 30 yards?
Thanks

Yep, something's not right. The pin should be pretty closely aligned with the arrow as it sits on the rest. Give us some details about your setup: What arrows you have (length, size and tip weight), what bow you're shooting, what draw length and what draw weight, mechanical release or fingers.

Eyeball the string into alignment with the grooves in the cam(s) and down the center of the bow's handle. Then look at the arrow. If you're shooting release, the string should split the arrow from nock to point. If you're shooting fingers, the tip of the arrow should be just visible to the right of the string (for a southpaw).

If your arrows are properly matched to your bow and your centershot is set properly, then it would boil down to a shooting form problem, but let's go one step at a time and check the setup first.

Thanks for the reply; I'm shooting a Jenneing Buckmaster 2000s @55 lbs/28.5 inch draw with a mechanical release. My arrows are 100 grain Easton alum. XX75 2314 30 inches.
Thanks

RE: Sight Pin
 

I agree with Arthur that the pins should be in line the the centershot of the bow. There might be some slight differences cause by your anchor position like shooting with glasses vs. not, but not much. You do need to eliminate the bow setup problems first before working on form.

RE: Sight Pin
 

2314 is the stiffest arrow for 55 pounds @ 30" on the charts. Since you're actually drawing 1 1/2" shorter than that, I'd say you're considerably overspined. Also, your front of center balance (which partly determines how stable your arrow is in flight) is around 9%. That's fine for field points, but could give you problems with broadheads.

I would suggest going to a 29" 2215 and a 125 grain head. You would gain a whopping 5 grains of arrow weight with that setup. Practically negligible. But your FOC would be nearly 11%. Much better for broadheads, in my opinion.

That's likely part of your problem, but it doesn't totally explain why your sight pin is way to the right. I suspect your centershot needs to be adjusted to the left. Do you have a pro shop in your area or an experienced shooter that you could get some first hand help from?

RE: Sight Pin
 

OK, I've lined up my sight pin with the centre of my rest and the rest is lined up with the string, but now instead of hiting the Bullseye I'm 8 inches to the right, with the setup b4 i was ushally dead on.

RE: Sight Pin
 

Try this. Stick a piece of masking tape across each limb, about halfway between the end of the riser and the axle. Measure from the arrow rest side of the limb to the face of the cam, then measure from the face of the cam to the center of the string. Add the two together and then mark that distance on the tape. Then do the same thing on the idler wheel end. That will give you a better visual reference for lining the string up with the center of the bow. It won't get you exactly in the right spot, but it is a good starting point.

You do need to get that bow to shooting arrows right down the middle though. Sometimes it takes more than a little tweaking, even a little cussing sometimes, to get it right.

You should to go to Easton's website and check out their bow tuning guide.

Another good place to get shooting and tuning tips is at Pauls.

I sure wish I was there to give you a hand in person, allunit. It's really hard to figure out exactly what to do without being able to see the bow, the arrow flight and your shooting form. All we can do heere is suggest things to try. If all else fails, you can move everything back the way it was until you can get some face to face help.

RE: Sight Pin
 

This is not unusual w/ most newer bows. Many of them have grips offset from the centerline of the riser. Recent Jennings bows, and the BM in particular has it's optimum range of centershot pretty far out from the riser. This is why your pin sits farther out.

I have not owned a bow in years that the pins lined up perfectly w/ the centershot, even though they paper fine.

If you bow papers well at 2 different distances, and you are hitting the bull, I wouldn't change a thing.

You can mess around a bit w/ arrowspine to get them to line up better, but you must keep in mind that even though single cam bows will paper well w/ several different shaft sizes, they rarely shoot the normal to weaker spines as accurately. Stiffer arrows group better out of onecams.

RE: Sight Pin
 

This isnt right. your rest and sight should be lined up.

RE: Sight Pin
 

allunit78,

There are some good archery clubs around your area that I am sure you can get some exccellent help with getting your setup correct.
The one that I know of the best is York County Bowmen, I believe they also have a website that you can get contact info from.

RE: Sight Pin
 

JeffB is right on. Listen to him. Offset grips can easily make for mis aligned pins etc. And I totally agree that today's single cam bows group better with stiffer arrows.
Paper tune your bow from two seperate distances for a starting point.
Then group tune your arrows.
Set your sights, and I bet they still won't be lined up. I have never had a bow line up totally either. At least a newer single cam.

RE: Sight Pin
 

Thanks for all the replys, You've all been a great help!

RE: Sight Pin
 

I've only shot Hoyt, Mathews, Martin, McPherson and Pearson solo cams, so I don't know about all the bows on the market. But I can say that not a single one of the bows I have shot had to have the pins out of alignment with the arrow.

I just don't see how any bow can tune to where the sights don't line up with the arrow. How can that be possible without the arrows' point of impact shifting left to right at different yardages, Jeff??

RE: Sight Pin
 

Arthur,

You are the engineer, you tell me! :)

Seriously, I don't have a concrete answer for you. But I can tell you that no bow in my collection has the sight pins lined up dead center w/ the string path. Some are more than others, but they all wind up being off. I do believe it has to do w/ the fact that many bows nowadays have a grip that is offset from the centerline of the riser. Possibly this causes an "overcompensation" in the pin settings to the opposite side of the direction the grip is offset towards.

I also think that the way a person looks through the peepsight has a major(and probably more prominent) effect.

Many people center the pin in their peepsight. Some people (especially w/ these newer round guard sights) center the pin *guard* w/in the peep for a more concrete reference. This will cause your pins to be sighted in one way or the other farther out from centershot.

I don't seem to have any problems at least out to 40 yards or so, and my arrow flight is good.

Jeff, you call me an engineer again and we're gonna squabble!!! I ain't no freakin' engineer, I'm a machinist! Us guys that make the stuff have to figure out how to make engineers' idiot ideas work.<img src=icon_smile_big.gif border=0 align=middle>

Sounds to me like what you are describing is torque. I know you're an experienced shooter, so I would have to lay the blame on the bow design itself.

If I had a bow that forced me to have the pins out of alignment with the arrow, I wouldn't have that bow long. Not a single bow I've ever had (at least since I starting shooting sights for field archery competition some 20 years ago) has ever had the pins out of whack like that.

You don't happen to use a C-Peep, do you?

RE: Sight Pin
 

you might be opposite eye dominant. If you are that will happen. Being left handed as I it will line up to the right of center and a lot of times you will have to get a longer sight pin. To check eye dominance with both eyes open point your finger at a distant spot. Close one eye at a time and which ever eye has your finger pointing at that spot with the other eye closed is your dominate eye. You can learn to shoot with both eyes open and that will cure it. Strangly, when I went to the muzzy zero effect rest I was able to bring my pin back in line.

I did that little excercise of yours when I bought the bow and I am left eye dominant and I bat left in baseball, and shoot left in hockey and archery but I write with my right hand, so I am &quot;right handed&quot;. Maybe it has something to do with my pin not lining up?

RE: Sight Pin
 

I doubt it, allunit. I'm right eye dominant, shoot guns and bow right handed, but write and use a fork (very important<img src=icon_smile_wink.gif border=0 align=middle>) southpaw. I'm pretty much ambidextrous with everything else.

Just wondering, do you wear glasses? Your frames could be interfering with your dominant eye and cause your other eye to actually do the aiming.

WELL!!!

IS YOUR BOW IN TUNE????
ONE THING TO CHECK THAT WILL NOT TAKE TO LONG , IS TO CHECK YOUR VANE // FEATHER CLEARANCE WITH THE CABLE GUARD.
IF THE CLEARANCE IS TO MUCH YOUR ARROW WILL SHOOT TO THE RIGHT.
FIRST BE SURE OF A GOOD PAPER TUNE WITH ONLY ABOUT 1/16&quot; OR LESS OFF FLETCHING CLEARANCE
