Rolling Thunder Game Calls True Double Features The Rolling Thunder Game Call True Double is built around a simple 2-reed diaphragm design that produces clear consistent turkey vocalizations without the learning curve of more complex calls. Because it is a hands-free mouth call hunters can keep both hands on their firearm or bow while still working a bird an advantage when a tom closes the distance quickly. The 9 length and 3.75 width fit comfortably for extended calling sessions without fatigue. Its straightforward 2-reed layout makes it approachable for hunters still building their calling skills. At just 4 oz the True Double disappears in a pocket or lanyard pouch so it travels easily into the blind or up a tree stand. The diaphragm format means no moving parts to maintain in the field unlike box or pot calls that require chalk or striker upkeep. Turkey hunters looking for a reliable backup call or a primary mouth call for everyday use will find the True Double a practical addition to their gear. It is available for sale at GrabAGun for spring and fall turkey seasons alike.
