I started with a box call, and both boxes and slates are easy to use. If you only have one call, make sure it's one that works wet. I put off learing mouth calls for a while because I thought they'd be hard to learn. They are harded than a box or a slate, but not that difficult. I picked up a 3 pack, left them in my Jeep, and practiced on my way to work--Picked it up pretty quick. One problem with boxes and slates is that they require considerable movement. If you don't learn to use a mouth call, consider an "egg" call, also known as a push/pull call (i.e., Knight and Hale's Tom Coffin). You can work these one handed with minimal movement when a gobbler is close enough to see you and you don't want to use a call that might give you away by moving too much.
Good luck.

Your best bet when hunting as a pair is to try and choose two trees within a few yards if each other to setup. This will allow you to communicate better. Setting up further away is okay, only if you have some years in the turkey woods and really know how the other person thinks. My brother and I have used that tactic many times, but we've been turkey hunting together for over 20 years.

I don't hunt out of a blind (too restrictive for me) but you would probably be better off sharing a pop up blind.

Definitely get a slate call. Slate is easier to get good sound on and needs less care than glass, crystal, or aluminum. Learning how to hold the call and the striker properly will go a long way to helping you call in a bird. Good luck.

You don't need to waste money on DVD/CD's.Just go to You Tube and you'll find enough vids to last a lifetime covering how to use every turkey call type in existence.

I didn't even think about that, that's a good idea. Thanks

The slate call is easy to learn,I use the mouth call a 2 reed version to free my hands up when they are coming in close. They are not that hard to use for the basic yelp and cluck,the purr is the hardest one I have learned how to do with the mouth calls. Start practicing now and you will get it down in no time. Also I learned a lot by watching hunters on Youtube and hunting shows,this helped me to know when and how to use certain calls. Good Hunting.
