I had a fellow bring a bear TRUTH by the shop a few days ago, and it did something that I have never EVER seen before.
We put a QAD Ultra Hunter on it, we center shot it, bow squared it and shot it. Had a bit of a high flight on release...so we made the adjustments....no change. Made some more....not a thing changed.
This went on for a hour and a half. I eventually had the arrow sitting about 10 degrees upwards....and STILL had a HIGH tear. We shot stiff arrows, weak arrows, and right arrows. Feathers, vanes and blazers. Wasn't a clearance problem like I thought....dunno what it was.]
Any ideas? Tiller heigth was correct...bow was brand new right out of the box. Everything in spec. Was the rest not dropping fast enough? Or was it maybe bouncing back and causing a clearance issue? Thats the only thing I can think of?

I run a shop also. Are you shooting the cock feather up or down?? If up is it hiting the top bar?? Did you try and remove the little top bar and see if it changed anything?? Will be interested in what you find out. Good Luck

Everything was in spec , did you check string and cable lengths ?
they orient the cam , which effects nock travel

What really baffles my mind, is that no matter what I did..the bow just did not respond to anything. I have seen one other bow do this before...it was an older Martin with those hybrid TAC cams....and either the limb was warped or an axel bent...but it would tear nothing but right....no matter what we did to it...exact same thing. Nuts...

Sounds like it might be a cam timing issue. As mentioned, a slightly over or under rotated cam can cause some pretty funky nock travel and a darn near impossible to tune bow.
Not to insult your intelegence but just asking some of the basic questions.
1) when you measured tiller, did you use the bow string or a string stretched between the axles? Setting an even tiller with the bow string on a single cam bow will yield a bow that is significantly out of tune.
2) Did you change the rest to something like a prong rest to see if it would tune with that? I have never used the QAD rest, however I have had a couple of bows that simply did not like a particular rest. They would tune fine with just about anything else.

Straight out of the box the cam should be in the correct position , Id try a different rest also .
Unfortunately we've all had a bow or 3 that would not tune no matter what we did .
