The Gobbler Gauge was developed to measure the spur and beard of the turkey. Fast and accurately measure the beard with our custom made measuring tape located inside the hinged lid. The tape measures up to 15 inches for beard length and also measures up to 100 mm for curved spurs. The depth of the Gobbler Gauge barrel measures up to 2 inches- 50 mm. The Gobbler Gauge and tape measure are made of plastic and the rivet is brass which makes it 100% weatherproof.
