First off, be carefull its addicting.

I learned to call turkeys with a slate. I still use it to this day for certain occasions. I felt it was the easiest to learn on. Not a steel or glass. I leared real fast that you will want to figure out the diaphram calls. Especially if you hunt alone. Start by scouting. Find out where they roost. You can do that with a locator call. Lots of loctor cals out there (coyote, owl, crow, goose, gobble, slaming your truck door

). If you have access to the property by roads start by driving in just after dark. drive slow and locate from the truck after they have roosted. Do not hen call at them. Sometimes its that easy o locate, sometimes its not. Once you find a roost you have just increased your odds. Get them coming off of it in the morning or going up at night. Dont call at them too early, timing is the key off the roost. Decoys are a must too, I dont always use them but very often. I hate blinds, most like them. I am closterphobic. I have learned to sit still.
Are they smart? VERY. They can see like you cant beleive. Sit still.
As far as learing to call. I like the Primos Truth videos. They can teach you alot from that front porch. Practice practice practice. My wife hates me this time of year. I go through a few diaphrams before season starts. While I am driving I even practice.
There is alot more to be learned but that is what I have for you for now. Lots of turkey guys on here. I am sure they will help out.
