A Penns Woods Turpin Yelper. Been using it for 35 years but like most I use and carry many and different types of calls and have favorites in each style. But if I left one out of my bag at home and got to my hunting spot to discover the fact, the the only one I would go back and get is the Turpin Yelper. I' ve made that drive back to get this call a couple times over the years,just can' t hunt without it.[]
