Hunter's Specialties new Ring Zone™ turkey calls -- available in slate, Starfire Crystal™, and Ceramic -- have a resonating surface 200 times larger than other friction calls and a special outer ring that work together to produce sounds in the 1,700-2,000 cps frequency range.
According to scientists, that is the range that turkeys produce in the wild, and hear best. The slate surface produces soft sounds. The crystal produces high pitch and volume. The ceramic gives you the volume of crystal and the forgiveness of slate.
