Zach,your miss of the beaver,is the exact reason I tell trappers to use a 330 at their castor mounds.I learned how to trap beaver using footholds,but there are so many variables to take into consideration when using them.
Even novice trappers that have called me for advice,catch beaver the first night after setting 330s at castor mounds.
It has been said that:a 330 has made poor beaver trappers into fair beaver trappers.Fair beaver trappers into good beaver trappers,and good beaver trappers into outstanding ones.
Good luck on your beaver venture .
WARNING----Beaver trapping is addictive----there are no 4,5, or 6 step programs to get over this addiction.Once you have triumphed life as you know it will never be the same.
