First thing to look for is fresh turkey scratch in the leaves. Where there are hens, the gobblers will find them.
Patience, patience, patience! Turkey hunting patience is a whole different ballgame than deer hunting patience.
If you don't have a butt pad, get one asap. The ability to sit absolutely still for extended periods of time is a must.
Don't over call, call every 5 - 10 min., while trying to find a gobbler. Once you've found him and he's answered your call, be very sparing with the calling, he knows about where you are and will find you if he's serious. Listen very closely for gobbling distance and leaf rustling, often they'll walk right in w/o much gobbling.
Once your set-up, always above the gobbler, face down hill, with your gun at your shoulder and be ready and still.
If there are two of you, have the caller above and behind the shooter by about 20 - 40 yards, often gobblers will "hang up" just out of shooting range of the caller.
Wait until he's within about 35-40 yds. and aim for the spot where the waddles meet the feathers, that will give you a better margin for error.
Relax, make the shot and fill us in on your hunting day!
Most of all enjoy your hunt!!
