What could have happened????

[Skeeter 58]

All right, here it is for all you tuner fellers.

A couple months ago I bareshaft tuned and broadhead tuned my new 2010 Z28 quite nicely. Broadheads hitting with field points.

Decided to switch back from a LimbDriver to a QAD. When I went out to tune it, bare shafts now hit wayyyy to the left. Broadheads hit way left too for whatever reason. When I say way to the left, its not only the POI, but the arrow is way nock right, point left. Like on a severe angle.

No biggie, right? Just move the rest a little. But no matter what I did, I could not close the gap between bh and field points.

Thinking I was having problems [again] with that QAD, I switched back to my trusty LimbDriver. Everything went back in the exact same place as I had it indexed.

Well, bareshafts still hitting the same place. WTH? This is not a little bit, its like 10" from 15 yards.

Same arrows, same bh, same everything. I checked timing, its still on, specs are close to the same, getting max dw within 6" of draw.

I put a couple twist in the cables because the dw was down about 1/2# but bareshafts still hit way left.

Now the only thing I can think of thats changed was a few days ago I noticed the lower speed buttons were way low compared to the upper ones so I looked up the specs and put them where they belong. But I dont see how that could make the diff in POI.
The only thing I've not checked was for cam lean. Do you all think that may be the problem?

Anyone have a clue what might of happend, or what I need to do to get this thing shooting right again?

Thanks.

Skeet.

Check for cam lean. That would be my guess.

If your bows tune returned to its true tune after putting the limb driver back onI would suspect that your having an issue with that QAD , maybe contact or something else .

Check for cam lean. That would be my guess.

Yep, thats the only thing I can think of too since it wont respond to no amount of tuning with either rests.

I hate to see this because it use to tune straight down the middle. But I've had to gradually move my sight over during the last month or so. I thought it was just the strings settling since the bow is still basically new. It has very few shots on it. My estimate would be less than 300 shots, if that.

Guess I will put it on my drawboard this morning and see if I can detect much cam lean.

Does any other of ya'll have any other idea(s) what could be causing this problem??

Here are some pics of the cams at full draw. I'm not really seeing much cam lean, do you all?

I have to say it is a rest issue and not cam lean. If the LD tunes fine stay with it. It is a much more bulletproof rest anyway. The QAD's are notorius for having contact issues.

Thats the problem. It wont tune with either rest. Bareshafts hit same place.

I even tried a under spined bareshaft with the same results.

I just noticed that there is slop in the bottom cam. Top cam is fairly tight. The only spacers I have makes it too tight and cant get the e clip on.

Guess I'll have to wait till Manday and see what Elite says.

Finally got it and I aint flippin believing what it was. Unreal.
