The slate and glass calls are awesome, but I challenge you to try their aluminum call! I have several that I try to use every year, but they never make the "cut". Their aluminum reminds me of a great glass call. It has the best tone I have used in aluminum. Zink makes some of the best turkey cals I have used in my25 years of chasing turkeys. I strongly recommend them.
I had the opportunity to run the calls down in Harrisburg. They knew right away I wasn't new to pot calls and I complimented them on the aluminum. Probably the best aluminum call I've ran however, the crystal and slate by far are better than their aluminum. I wouldn't hesitate to purchase the crystal or slate. If I wanted strictly an aluminum, I'd buy theirs.
