The Flextone Thunder Gobble is a totally new design in gobbler type calls. Its ergonomically shaped mouthpiece not only fits your mouth comfortably, but it directs 100% of your wind through the tube to produce super loud gobbles. The double reed construction allows for raspy tones, which add realism to your gobbling that you can't get out of shaker type gobble tubes. The Thunder Gobble is the perfect call to use to shock a gobble out the wariest of old gobblers. Use it in conjunction with hen mating yelps and cause that jealous ol' Tom to come running in for a fight. This call has proven deadly on late season call shy Toms.
