The advice I always give folks is learn to be an outdoorsman. A lot of guys think that just because they hunt they are outdoorsmen......WRONG!
Turkey hunting requires patience on most days. It never goes like the videos. You also need to be really aware of your surroundings. Knowing the lay of the land is huge. Be aware that every sound you hear might be another hunter and not just a turkey.
BE 100% CERTAIN OF YOUR SHOT! Do not shoot at something that "might" be a turkey or a gobbler....KNOW THAT IT IS! The excitement doesn't come from killing the bird as much as getting him to step in the open 25 yards away. PLEASE DO NOT do like some guys on these videos that hide behind tom decoys and crawl up on birds.
On your gun....If you have a full choke to screw in do so. You can also pick up a turkey choke for 25-30 bucks. Get a good vest or cushion. You WILL have body parts that go numb, usually in the behind area.
You will need to be in the field a lot of days to really start to understand birds. Hunt.
