Your main concern should be finding the roosting sight. When You blow a locater call and hear a gobble truck on towards it. Do not wear the bird out with a call every two minutes. If you can hear the bird you sould be close enough to find him, unless you're hunting ridges. One pieceof equipment that is a must is a good set of binoculars. I twnd to walk 20 30 yards and stop and listen if there are birds roosting near by you will hear some tree yelps, fly down cackles and some other turkey vocabulary. If you bump a bird once it shouldn't matter. You need to train yourself to look for a turkeys jerky movement on the ground. I use my ears just as much as my eyes for putting and yelping. Certain locator calls work for me and some do not. Mix it up, I have the least luck with a crow call. Try a pileated woodpecker call it is loud heck and really will get a response. If you roost some birds the night before than I would try to get at least 100 yards from the site and in the direction the birds usually fly down and walk. I would not blow a locator since you have them located. Let them wake up and start talking, if you are not close enough you may have to circle way out of the way to get closer, but that is just the game. Your main concern should be the roosting site. Find this and 80 percent of your challenge is complete.
You need to look for funnels, fields,on your maps, turkeys are just like deer and will take the path of least resistence while walking through the woods. Look for open wooded section where a hen will have the ability to see a gobbler while he struts. Like I said you are doing the riight thing, just keep at it remeber to use your ears as much as your eyes, and take your time.Do not be afraid to get to cmove towards the gobbling that you hear, but move slow stop evey 20-30 yards and survey your surrondings and listen. There is not a magical call out there that will make a bird gobble everytime. Think about going to a basketball game and everytime someone scores you yelling at the top of your lungs, you are going to get horse and stop after a while. I have seen a gobbler, gobble himself horse before competing with two other gobblers. Persistence pays off in big ways,and so does patients. good luck hope this helps.
