The Ol' Betsy is built with select Pennsylvania slate. This slate combined with the acoustical cup and internal sounding board gives you a slate call that can do it all. The Hardwood Striker only adds to the versatility of this call giving you yelps and cuts that reach way out or finishing calls for close calling. Slate is the easiest surface to use and produces the purest turkey sounds. It is the perfect finishing call with its soft yelps, clucks, and purrs.
