Don't worry if you sound like the pros on TV when you use your call, you will get better with experience. I have heard quite a few calls that I thought was a novice hunter that turned out to be a turkey, they can make some god awful calls. As was already, scout religiously and don't run around the woods calling while you are scouting, just go to a spot in the woods and sit and listen, both early morning and evening. If you don't hear any birds, go to another spot, repeat until you find several places that holds birds so you can have a plan B if someone beats you to your spot. Movement more than anything else will give you away and when you do move, do it very slowly and don't move when a turkey is not facing away from you, they have a great field of view and peripheral vision. Let them come in close before you shoot and shoot for the base of the neck. Good luck
