The Hook Up box from Primos is designed to take all the guesswork out of getting that perfect box call sound every time you play it. The ultra-strong magnet holds the paddle at the perfect angle for crisp cuts, smooth purrs and soft to loud yelps. When used with the included Gobble Band, the Hook Up produces some of the most realistic gobbles ever made. The detachable paddle can be removed for silent carry. This call is simple to use and fun to run.
