Pot & Peg Calls
Technically speaking, a "pot and peg" is a type of friction call. Its name describes its two main parts. The "pot" (also known as a "chamber") is a shallow, round, hollow bowl that holds a hard, flat calling surface. You pull the "peg," (also known as "striker") along the calling surface, just as you would if you were writing or drawing on the call's surface. The resulting friction produces a vibration that, if done correctly, sounds like the natural voice of a wild turkey.
Pot Call Types
The "slate" call is the most common kind of pot call. Slate calls got their name because striking surfaces were originally made of slate-a layer of fine-grained, metamorphic rock. But now, more and more manufacturers use other materials. The different types of calling surfaces include:
Crystal (purified glass)
Aluminum is lightweight and pliable enough to tailor when crafting a turkey call. Some manufacturers use a more durable anodized or coated aluminum, often with a non-glare finish. Ultra-dense ceramic, customized and manufactured specifically for turkey calls, is a popular and relatively new material. Crystal is a more purified version of glass. Technical processing results in a clean, clear and higher-grade material that is harder than common glass.
Power of Pot Calls
The core of a pot call's super power is the huge range in pitch, tone and sound frequency they possess. The variety of materials used to make the chamber, sounding board, calling surface, and striker combine to provide you with a wealth of different sounds and calling options.
For example, a call with a walnut wood pot, hardwood soundboard and slate surface will have a lower sound frequency and a deeper tone and pitch, compared to a call featuring a composite pot with a glass soundboard and harder aluminum surface.
Multiply the different types of calling surfaces (slate, glass, crystal, aluminum, ceramic) with various sounding board material (glass, hardwood or plastic-composite), plus the variety of possible strikers (carbon, aluminum, acrylic, rosewood, or hickory)-and your call's sound is powered by a seemingly endless range of possibilities!
Pot calls also have the ability to speak the entire turkey language. Pots can produce clear yelps, yet also break right into a raspy yelp without missing a beat. They do an awesome job clucking and cutting, yet they easily roll into very seductive purrs. Most hunters can yelp on box calls and mouth calls, but they need a pot call to create good purrs and other soft sounds.
Pot Call Popularity
Pot and peg turkey calls are very popular among hunters. One reason is that calling techniques can be learned fairly quickly. Just by reading the directions on the back of a call's package, by watching a quick demonstration on video, or by watching an experienced turkey hunter show you how. Soon, you can be making good, consistent turkey sounds. With practice, you will improve every time you play the call.
