Forget about it. I see more disappointed first time bow buyers that bought a bow like this from a pawn shop or garage sale because it was only $50. When they come in to the shop and ask me to fit the bow to them 95% of the time they are SOS because you can't get parts for these dinosaurs any more.
I doubt the draw length will fit you so it will need to be changed and you can't get parts any more.
If a limb cracks (they may already be cracked) you can't get parts for it any more.
The string on that bow definitely needs to be replaced so you are looking at additional $$$$ for a string, cables and labor.
You are gonna want to replace the old and broken accessories it has on it right now so that is additional money.
Honestly, by the time you put the money and time into getting this bow ready to hunt (and you may not be able to) you could get yourself a brand new package bow like a PSE Brute Parker blazer, or Mission menace that is current production, has a lifetime warranty, comes with modern accessories, is gonna be a hell of a lot quieter, more forgiving and pleasant to shoot, it can be adjusted to fit you properly, so on and so on and so on.
