You buy the bow to match your draw length.
Bows only have so much room for adjustment.
Look at the sticker on the lower limb.......should tell you all the info. draw weight, let off, axel length, draw length, etc.....
For deer hunting you want at least 60.....I have shoot 82 for years.
Bear.....no way for 90......They aren't that much new.
Also you don't know what has happened to this thing.
Some idiot could have dry fired it a bunch of time.
The last thing you want it a bow blowing up on you.
It can get ugly.....had a buddy get a broke nose when his PSE went.
