A slate housed in a dense ZEBRA wood bowl. The striker is a specially designed Osage orange wood with a wide foot on the base making it easy to use for the BEGINNER. Both are a very dense hard wood that transfers the sound out of the call efficiently. This call produces yelps, purrs, cutts, putts, fighting purrs. An extremely user friendly slate that holds up under constant use of working a bird, and sounds good enough to put in the veteran hunters turkey vest who appreciates quality sounds and well-made calls. This isn't just a call ... This is an INSTRUMENT that plays turkey!!
