Waterproof. It's Hurricane season and this box call doesn't mind. The Hurricane Box call has been built with new technology eliminating the need to maintain the call. The new Ergo-Grip paddle handle is designed so you can sound like an Old Hen or Young Hen on the right or left side of the call. This call will work equally as well on wet stormy or hot dry days. Due to the special new coating this call should never be chalked or sanded. Sanding will damage the special waterproof coating.||||||||||
