    Went out to shoot this afternoon and went to pull back my bow and couldn't have drawn it more than 6 inches before the string popped off the cam. The arrow flew maybe 5 feet and thankfully I was OK. Just wondering what could have caused this. Googled it and it seems to be a problem typically experienced when torquing on a let down. This was definitely not what I did today. Plus, I was utilizing proper grip so I doubt torque was an issue. I'm shooting a Diamond Iceman FLX. I'm going to take it in tomorrow, but was wondering if you all had any clue what would cause this.

    Did you let the down down before that or was it a shot?

    I would think it would be hard to derail it on the draw.

    That is really the only reason why a string would derail. Having done some snooping around as well your bow is particularly finicky as far as the draw stop and correct post position. Check the spacers between the limbs and cam. I can't really say what was the exact cause was, but thankfully your alright.

    EDIT: My bad for referring you to another forum, but seems like multiple people have the derailment problem as far as the cam timing. http://www.archerytalk.com/vb/showthread.php?t=1444543&p=1060337057#post1060337057

    How did your arrow fly off if you were hooked up to the string and pulling the bow? The only way you cold have derailed a bow while pulling is by torquing the holy hell out of it.

    It was the first shot of the afternoon. Hadn't drawn it yet until then. Needless to say, I was a bit frustrated!

    Now I'm confused myself. You're right, the arrow shouldn't have flown off if it was a straight derail. I must have hit the trigger somehow. However, the fact remains that my string came off the cam.

    Any damage to your strings/cables? Possible to post pictures?

    +2, pictures to describe situations/problems is like going into the chicken coop and finding a golden egg.

    It's possible the release came off the loop. A loop can slip through a caliper style release,just a thought.

    I watched a Diamond derail in my garage.Wasn't torqued at all. Guy pulled the release and the bow stayed at full draw by itself. I started ducking because I knew what was about to happen could't be good.The best I can figure is it got caught on the draw stop peg and hung up,until it slipped past.All hell broke loose when it did.:lol:

    Had a customers Bear lock out on full draw one time for me. Was scary as hell. I held on for dear life and we managed to scramble back to the shop and get it in the press:sheep:

    Here are a couple pictures. The string look great and I don't think it will need replaced.

    Maybe something was caught in the cam groove.

    x2, its a difficult question and ive seen enough go wrong to know, theres also the chance you derailed it but when it happens so quick its a shock and hard to recollect what has occured.

    Yeah, that's always the problem. The bow tech said it looked fine. Seems alright now. Hopefully it was just a freak accident. Just glad it happened before the season not during!

    If this bow has a cable slide, you may want to make sure it is sliding correctly. I drew on a nice buck last year and had the string fall off the cam. It was always a little sticky during late season. Replaced it with a teflon slide and it is smooth as silk now.
