I have quite a few custom calls of my own, and each one I have I have taken to the woods to see how the Turkeys like them, sence they are a better judge of sound than me. Some custom calls are Great like Tom Laska's calls for example his will call turkeys. "BUT" It has a lot to do the part of the country you are in too. There are a lot of custom calls on the market today, Proturkeycaller makes a Great Custom Call has Great sound and it will call Turkeys too.
