This is an excellent call for locating coveys before sunrise to come back and hunt them later. To produce the covey sound you simply blow into the call and say WH-ITE. Cover the hole with your index finger for WH and release slowly on ITE. The Bob-White sound can be made by covering the hole on "BOB" and on "WHITE". These calls are made from space-age heavy-duty plastic to ensure dependable performance all day, every day. Convenient snap for attaching lanyard (lanyard not included).
