The Diver Duck Call from Buck Gardner is extremely easy to operate and produces a variety of duck sounds. It stimulates all the noises made by Ringneck, Bluebill, Canvasback, Redhead, and Bufflehead ducks. Opening and closing your fingers will give the call higher and lower pitches needed for the various species of divers. Ringnecks and Bluebills have a higher and lower pitch, Canvasback have a deeper, but softer, call, while Buffleheads have a high pitch call; all of which are possible with the Diver Duck Call. When divers are at a distance, start with a loud quick set of high barks. As the flock nears, lower the pitch and add sharp BARKs for added temptation. This effortless blowing call gives you another tool in your arsenal and is a must on every lanyard in diver country.
