The Nomad Design Madmacs Sinking High Speed Lure range of super high speed trolling lures comes in 3 sizes - 6, 8 and 10 inches. Developed for high speed trolling, the 6" and 8" are capable of a max speed of 20 knots with the 10" rated at 15 knots. More than a high speed trolling lure the Mad Macs features the patent pending Autotune system which allows the MadMacs to always troll straight and run perfectly fish after fish. An added benefit of the Autotune system is an amazing action that kicks in at lower speeds of even 5kn. The ability to troll at a large range of speeds makes this a must have lure in every spread. The Mad Macs will run at a depth of around 8-10ft when trolled at slower speeds and around 3-4ft depth when trolled super fast. Featuring Metal Matrix machine-stamped stainless steel plate & HD ABS construction, it is one of the toughest lures available, and is up to any challenge. Finishing off with heavy duty terminals, the Mad Macs are fitted with super strong BKK hooks and Heavy Duty split rings perfectly balanced to each size model.
