Two summers ago, I purchased a Martin Trophy Hunter for my father for father's day. I bought the bow because we used to shoot an old Bear compound together and always enjoyed it, but eventually I gave that bow to a friend in the army. The new Martin wasn't shot for a couple months after being purchased, because 1) I bought it about a month before father's day, and 2) it was storming pretty bad the day I gave it to him. Thanks to the time gap (and my own ineptitude), I lost the receipt before ever shooting the bow.
On the first shot, the shooting string slipped off the idler wheel. This somehow caused the arrow to wrap around the front of the bow (carbon fiber), and it more or less shattered in my face, and the arrow tip actually went backwards. We set the bow in one of the barns while I looked for the receipt, but I never found it. I've been wanting to go back and see if I can get it fixed, but as the only other bow I ever shot was the old Bear compound, I am by no means an expert. So a couple questions...
1) How difficult would getting the string back on the idler wheel be? I've only ever restrung a recurve, again, not going to act like I'm more of an expert here than I am. I am a newbie when it comes to compounds.
2) How concerned should I be about the fact that the string came off the wheel on the very first shot? I'm not sure if it was a fluke accident, or if maybe that means one of the wheels is slightly misaligned, or if there's any known common reason to cause that.
I can provide pictures or other additional information on request. I'm hoping someone with more experience can help guide me as to whether it is worth trying to repair this particular bow (and what that may entail), or if the string slipping on the first shot means there is a mechanical issue and since I cannot find the receipt, it'd be safer to just look for a new bow. No one got hurt the first time around, but I can do without another arrow exploding in my face.
Thank you for your time,
Edit for some additional information:
1) Make was Martin, model was Trophy Hunter. I don't know the exact trophy hunter model or how long it had been on the store floor (purchased from Dick's Sporting Goods in Champaign, IL). Bow No. is 0816841
2) This was a 55#-70# model, I lowered it to 55# as per the manual instructions (my father has a bad elbow).
