Should you buy a new bow????? Well, that depends on what you are shooting now, if anything.
The bows Cabelas sells are every bit as good as any other bow out there they just don't have protected territories like Mathews, Bowtech, Hoyt, PSE pro series, etc... Our shop sells some of the same bows that you can find in Cabelas.
The PSE bow madness is a damn fine shooting bow and would be my pick.
If you already have a good bow you might want to upgrade the accessories, new arrows, game cameras, GPS, etc...
