RE: A few questions for the Turkey experts...
You'll have to pattern your gun to really see what work's the best. I prefer Hevi 13 6's. Turkey loads are expensive so get with a few buddies and pick out a few loads to try and split the costs.
I've been through the full gammit of vests, etc. to carry my "arsenal" of calls and for the last 8-10 yrs. (been at this 40 yrs.) I've settled on a fanny pack. Works for me.
Decoys- When I blind hunt I use em but I much prefer that up close and personal feeling of runnin' and gunnin' and I don't use em then. I travel pretty light. Being as this is your first season IMHO I think a few well built ground blinds, decoys and a comfortable seating arrangement are in order. You'll have a lot more success.
Locator's- Almost any "loud" noise works. If I could come up with a device that would mimmick thunder I'd be a millionaire. Best thing is you really don't need anything,esp. if your blind hunting, "mother nature" provides em. What I mean is "listen to the woods". Anytime you hear a woodpecker, crow, owl, goose, coyote, door slam, horn blow, squirrel chatter, gobble, etc etc you get the idea- "listen". Now if your gonna run and gun probably a good loud crow call is in order.
Fighting calls- They work but it's probably something you don't need to worry about just yet but if your so inclined just use your pot call, your hat for wing beat sounds and your feet for ground sound. I use a mouth call and pot calls to mimmick fights.
Calls- Box call,potand a push-pin to start out with and start messing with some mouth calls. I really like push pin calls for close in work for a new hunter and don't forget scratching in the leaves is probably one of the best close calls there is.
Above all- "Have Fun!!". This really isn't rocket science and you'll find that most calls sound better than the real thing.
Be forewarned: This way of life is extremely addictive and can be hazardous to your health. lol
