Save your money, and tell any customer you may have.....they should learn how to use a mouth call and get a tube.
I'm telling you......those kits are POOR.
If I could make a bugle call that sounded as good, or better than a mouth call, I could sell them QUICKLY.
There's just no way to 'turn' a functional, easy to carry tube for a mouth call.
No, I am not an expert elk caller or elk hunter. I am just listening to my customers, and learning how to use the calls that are available in the market.
