Did I break my bow?

    OK, so I am pretty new at shooting compound bows, used to shoot a recurve when I was younger. I am good with my compound bow but am by no means a pro or expert and I have only had this bow (my first compound bow) for two or three months. Today I was out shooting and hitting my usual 1" groups at 25 yards. Then something strange happened. As I was drawing, I got to maybe 1/4th draw and my arrow popped off the string. My friend who I was shooting with said there was a loud pop but I didn't notice it. I thought it was just a fluke and laughed it off. I picked up my arrow and renocked it and began to draw. Once I had drawn I realized that it was much much easier to draw this time. I released my arrow and it shot way high missed my 18"x18" target completely and hit my back stop. I tried drawing again and noticed that, again, it was ridiculously easier than normal. Felt more like 30# rather than 60#. I also noticed that my arrow rest was not fully engaging which I thought was odd. I carefully inspected my bow and could find nothing wrong with it. Now again, I don't know that much about compound bows, but nothing looked broken/out of place, everything looked fine. Any ideas what the problem could be? BTW I have never dryfired the bow. I have never even pulled the string back without an arrow nocked.

    Thanks,
    Chris

    I am by no means an expert or have any experience in compounds seeing how i'm new. But, maybe:
    -the limb bolt came loose
    -a cam bolt came loose

    Check the tiller lengths or maybe check to see if the cams are engaging at the same time.

    I'm sure someone more learned can help you out, but those are my newbie thoughts

    You said that it had a pop then you said that the rest wasn't fully engaging. That took me straight to down cable. Look at your top cam and see if the down cable (the one that is connected to your rest string) and see if it is still in the cable groove on the cam. Could be top or bottom. If this is the case, your bow needs to be put in a press and put the cable back on. To keep this from happening again (given this is the problem) the bow is probably experiencing some pretty bad cam lean causing the cable to come out of track.

    I do not recommend you trying to fix this. Take it to a shop and have them take care of it. It is possible it is something else but, I highly doubt it's what the above poster suggested. Neither of which would cause the rest not to engage. Oh and not very many bows have cam bolts. BowTech has bolts to hold the cam axle housing in place but, the cam still only has an axle.

    I had an old Proline bow that had the outer bushing under the limb bolt break and disintegrate. It happened on the shot, heard a loud snap/pop and I didn't initially see something was wrong until I tried to draw it back and it was much easier. That's when I realized the limb bolt was directly in contact/holding the limb in place. Compare the top and bottom limb bolts and the bushing/spacer between the bolt and the limb to see if there is any difference.

    Ya always make sure you draw your bow straight back a lot of people will tilt or twist their bow while drawing because their draw weight is to heavy and roll their cables or string off, but it doesn't sound like you did that since you said everything looked like it was in place, your best bet is to take it to a shop like sticknstring said.

    Thank you all for the advice. I am at work right now so I can't look at it. I will be sure to check the bow more closely when I get home (in about an hour). I'll let you all know what I find. Thanks again!

    OK. I think I found my problem.

    I think this screw is supposed to have a head.

    This red piece moves around an awful lot. I hope this is an inexpensive and easy fix. Does this look like it could be the cause of my problem?

    I'm no expert but i'm pretty sure there is supposed to be a screw there if you check the other cam there should also be something like that. see if there's a screw there if there isn't then its something else.... really nothing should move on your cams.. I would defiantly take it into your shop asap.

    IIRC that is just a pin, not a screw. Definitely broken. PSE should warranty it. Take it to your shop and do not put any more arrows through it.

    On a side note; this was probably caused by your mods screws coming loose. Good lesson to periodically check your bow over for loose parts.

    That's what i meant by a cam bolt. I guess my semantics were a bit off. Adjuster screw? draw length adjuster pin? I don't know :sheep:

    The torx screw circled is loose. Judging from wearing, it looks like it should be where the arrow is pointing.

    I'm gonna take it down to my local pro shop tomorrow hopefully. But no, I will not be putting any more arrows through it till it's fixed. :D

    Is that a Stinger 3G? When I bought mine last year there was an issue with the screw being loose in the red piece. I called the place I bought the bow from, and they said to just use some blue Loc-Tite on the screw and it would be fine. I did what they said and never had any other problems.

    Goosepond, thanks for the tip. As I am new to the world of compound bows, I am going to let my local pro shop handle this one once pay day rolls around. The guy here in town sells only PSE bows and is licensed for warranty work. In response to your question, no, it's not a Stinger 3G, it's a Drive. Thanks again for the tip. :D
