By simply pushing a rod you can make realistic purrs, clucks, and yelps. Push-button calls are well suited to soft calling when birds are close, and also to simulating gobbler fights by creating loud purrs. Like boxes, though, push-buttons don't work when wet. Slate calls are made of slate, glass, or aluminum. The caller scratches a peg across the surface to make lifelike purrs, clucks, and yelps.
Many hunters choose slates for quiet, close-in calling.
Traditional wooden-peg and slate calls won't work when wet, but glass and aluminum calls used with graphite pegs will work even in a downpour. Gobble shakers , a kind of bellows call that you shake in one hand to produce a gobble, will often make turkeys gobble in response as well. Gobble shakers are best used after shooting hours to locate roosted turkeys, when there's no danger of attracting other hunters to your position.
