Someone referenced this same kit in the mouth call making discussion section a while back and thread and comments are still at the top of that section. Here are my first thoughts on it again...
"That kit looks similar to the Call Purrfect kit that has been out for decades. I had one way-back-when but found out before too long that it is pretty limited in what you can do with it in terms of reed tensioning...a factor that is very important in making calls. I'm sure you would be able to make calls that will make turkey sounds but, quite honestly, there are better methods of making calls, including not using any kind of jig at all.
My advice would be to order call-making materials from a supplier (you will be able to get a lot more call-making materials for your money that way) and either get another type of jig that gives you more range in reed tensioning...or use a jig-less method of call making altogether. If you go to another type of jig, you want to get one that allows you to vary the reed tensioning/stretch. If you need more information on materials, jigs, or jig-less call making, I'm sure the folks here can help you out with recommendations.
Also, lots of good advice and answers to questions you might have can be found in previous posts in this section..."
