The Phelps Maverick Signature AMP Diaphragm Elk Call has been specially designed to meet the demands of World Elk Calling Champion Dirk Durham. The Maverick elk call features a unique reed that produces authentic bugles and lifelike cow calls. The latex is stretched to the optimum point, ensuring the longest possible duration of realistic calling. Because of this, it will take about 20 hard bugles for the reed to settle in before it reaches its most lifelike tones. Create more realistic sounds on your next elk hunt with the Phelps Maveric Signature AMP Diaphragm Elk Call.
