Flextone has taken the features of tube type calls and combined them with shaker type calls to create the new Thunder Gobble. This Evolved Flextone Gobble Turkey Call creates realistic raspy gobbles. The ergonomic mouth piece of this Flextone Thunder Gobble directs 100 percent of air flow through the call to produce super loud gobbles. This turkey call also includes a lanyard for easy carrying. These Flextone turkey calls have a replaceable voice for years of extended use.
