There are a few things you should know in order to maximize your effectiveness when hunting turkeys.
Turkeys are extremely sensitive to sudden movements.
If you move too quickly while a turkey is in view, there's a good chance you'll spook him. Keep all movements to a minimum, and if you do have to move, move very slowly. Use your turkey calls together, but do not overuse them. In order to fool turkeys, you must make a variety of sounds. This means using both your calls in combination.
