First time I ever went turkey hunting was in 2010... only time I went that year, and it was with a friend on one of his hunting spots. He did all the calling... before birds flew down at dawn, he hit a gobbler shaker once or twice. Got all the birds gobbling in the trees. Then he used a mouth and slate call to get a gobbler almost in range, but then the bird saw the struttin decoy and backed off.
Haven't used a gobble call myself while hunting, and don't plan on it really unless I know it's a dominant bird or something.... also I mainly hunt public land, lol
