The Stupid Tube™ by Secret Lures is a custom designed tube and jig head that work together as a system. It pairs with the standard Stupid Tube Jig Head in 3/0 or 4/0, the HD Jig Head is too large for the 3.7 Stupid Tube. The Stupid Tube itself is a 3.7-inch hand dipped salted plastic tube developed with Terry McWilliams (2007 Bassmaster Classic) and Matt McCoy (2012 Bassmaster Classic). They both credit this system with their trips to the Bassmaster Classic and the success stories didn't stop there! Most recently, Nick Ratliff used the Secret Lures Stupid Tube for key fish in the 2018 Bassmaster College Series Classic Bracket, where he walked away with a trip to the 2019 Bassmaster Classic of his own. The Stupid Tube has been the officialSecret of big catches and big wins for over a decade!
