Preston’s Black Diamond from Pittman Game Calls is the original diamond cut diaphragm, first of its kind and introduced by Preston Pittman. Built with ultra-thin specialty diamond-cut rubber, this four-reed call set the standard for versatility in turkey calling.

Known as one of the most versatile diaphragm calls on the market, the Black Diamond produces a raspy, realistic sound that works across a wide range of calling situations. Despite its performance level, this call remains forgiving. With a little practice, even beginners can successfully use it while experienced callers can push it into more aggressive sequences.

From soft calling to stronger, more assertive sounds, Preston’s Black Diamond remains a proven, go-to diaphragm trusted by turkey hunters season after season.
