My buddy just xcalled and told me his widow psr is throwing the string when he draws,  sometimes off the top limb sometimes off the bottom limb, he tells me he has checked all the obvious problems such as twisted limbs ect. I told him I would post it here and see if anyone has any ideas!!!!!!!!!
     thanks

Was that a PSE Widow.check the string loop

Its a black widow PSR recurve and the grooves seem to be good

Probably a bend or crack in the limb,the wise one's here will definitely know what's up for sure.Their is more knowledge here than you can get in any library.Good luck with it.

String loops are tight enough?  Did he just put a new one on, or did this suddenly develop with the old string?
I'm hoping for his sake that is all it is because the other reasons are not as good.    

same problem with different strings..

I had the same thing happen to my Bruin.  I strung it up did a couple of short draws to make sure it was set.  Got up in the tree stand, drew back to full draw and then wham.  My bow is 15 ft below me on the ground.  

I know my limbs are not cracked, or twisted.  It does have bow hush on the the string near loops.  I have not tried a new string yet. I was thinking some how the loops loosened up. or the hush was making the string slip.

Havein the bow fly out your hand is quite the eye opener.

Call Black widow, they are good folks and are more than willing to help, even if you did'nt buy the bow from them.

He has got an email off to black widow already just not got a response yet.

Could it be the diameter of the string loop maybe to thick,to many strands? did he use a synthetic wax on them?

The string is a black widow string, and as far as i know he uses beeswax

when I first got my psr, when I would pull back but not release. the string was off the grove on one lime, so I called BW and they ask if i had the sure grip, and if so, put some power on my hand and don't grip the riser so tight. it will make the bow twist. low and behold, it worked. the sure grip and the sweet on our hand don't mix. thats my 2 cents

widow will get back to you... they are great and go above and beyond the call every time i have ever heard of a problem with them

That is interesting. Sounds like you checked out the obvious. Let us know what you find out. I owned a PSR with no issues. I have full confidence in the Black Widow people.
