To me the easiest calls ,or turkey vocabulary if you will allow , is made on a box or slate. But then too, I haven't been around the world nor handled all that many of either type. I have in the past tried to carry ALL my calls while hunting. The last few years I have lightened the load considerably. And I have grown to be very fond of a particular manufactured slate . With a carbon striker it'll sing like the sweetest hen of the flock. With a hardwood striker it'll make some good gobbler talk. I experiment a lot with all my calls. But once the wood or slate has got a bird committed and it is making tracks in my direction, I'll go to the mouth call. The more real turkeys you can listen to , combined with daily practice , no matter which call you are using, or all of them , will make you a better caller . End result will be you in the woods and working a bird and you'll be able to make any turkey sound ,at any given moment , in any situation. Can I do that ? NO but I have only been using mouth calls for 28 years .For me the hard part was finding a particular mouth call that fit me and made a lot of noise with little effort. I have gone through dozens. They are my favorite and I have 3 in my pocket every day of the year.Seems like you are doing the right thing. SCOUTING , SCOUTING, SCOUTING, it's a must . I ain't the first to say it,''woodsmanship has killed more birds than world championship calling'' Keep up the good work. later ''oldschoolturkeytactics''
