Hi beefjerky! Welcome to the forum!
Well. You have the first of many steps completed. Locating turkeys. But you need to learn about them now. Come spring the flock will be broken up and most if not all may noy return to the area you had seen them in. Alot of things can change where the birds go. Scouting will tell you where you need to be for first day. but be careful not to get too close to the birds, otherwise you might spook them and they may change their pattern. Find where they roost and find out where they are feeding, dusting areas, and what general areas they are traveling in once they come off the roost. Although it is very tempting to do so DO NOT use your calls before season! You can use locator calls to help you keep track of their movements while scouting but don't OVER use them.
A box call is a great choice when starting out. Get a cd with live turkey sounds so you can learn what the different yelps and vocalizations mean. Knight and Hale have a great series called Spittin feathers. Great cd's if you can find them. As for other gear you might need. Most of it will end up being what you prefer. Your first couple years will find you pretty much carrying everything but the kitchen sink. Try to start out light. A vest, a couple different calls, crow call, owl call, water, pruning shears, face mask, flashlight, small first-aid kit, a decoy if you intend to use one, a comfy seat or cusion, camo gloves, good boots,something waterproof.
Also, it would be a good idea to get a couple videos. Hunters speaicalties has a good series called H.S. University. The first of them is "So..... You Want to be a Turkey hunter" It has a lot of information that could help you out. After all of that you then need to pattern your shotgun. Get yourself some turkey targets and fire your gun starting at 40 yards. See what shot and choke combos work best for youe gun. Knowing the effective range of your gun is important. When i test my gun every year I shoot while sitting in my turkey seat since that is how I will be shooting in the woods.
I know it all seems like alot of work, but trust me. When you hear your first gobble of the season fireing back at your calls you will look at all that work as a pleasure. Remember safety and think of every turkey sound you hear in the woods as another hunter till you can actually see them. If you see another hunter in the woods getting close to you SPEAK to him. Don't wave your arms or hands at him or he might mistake you for a bird and shoot you.
Hope I have helped ya out some. Good luck!
If it gobbles,runs on gas, or is married to you it will give you trouble!
