Developed by legendary Japanese lure designers Yuki Ito and Shinji Sato, the Megabass Big-M 4.0 is a magnum sized (5 inch length, 2 ounce weight) deep diving crankbait that was created to dive to 13 feet and better adapt to big bass lurking deep. Using a flat sided design, the Megabass Big-M 4.0 generates a side-to-side rolling type action, which digs into the bottom more effectively than standard wobbling type crankbaits and produces a vivid flash that is more clear in deeper water where there is less light.
The Megabass Big-M 4.0’s unique shape and slender bill design creates less resistance, making it easier reel with more sensitivity when it comes into contact with structure as well. Pushing performance and innovation even further, the Megabass Big-M 4.0 features a heavy weight transfer system, which allows it to cast like a bullet in any condition and produce a loud knocking sound to attract big bass from a distance. The Megabass Big-M 4.0 is also pre-rigged with two oversized razor sharp treble hooks that provide lightning fast hook sets and the strength needed to handle aggressive fish. Finished with 3D eyes, gill plates, textured scales, and a custom paint job, the Megabass Big M 4.0 is the weapon of choice for anglers who are looking for the most realistic high performance big bass crankbait on the market. Available in 7 highly-detailed colors.
