i've got the one that has the hen sound on one side and the gobbler on the other side. it has worked well for me over the years, so much so it would be the last call i gave up if i ever had to get rid of them.
That's the World Champion. Have one myself that my dad bought in the mid to late 70's. Carry it myself now.
Would like to get the Fool Proof just for the smaller, easier to carry size.
