Megabass Big-M 4.0

Price from £ 25.11 View products

Big Profile Mid-Depth Crankbait with High-Flash Rolling Action

The Next Evolution of the Big Crankbait The Megabass Big-M 4.0 represents the evolutionary result of decades of big crankbait development. Moving beyond traditional fat-bodied, long-billed deep divers, the Big-M adopts a refined flat-side profile, short lip design and a low center of gravity to achieve a sharper, more dynamic rolling action. Designed to trace the productive mid-depth zone around 3.5m (11–12ft), it delivers an overwhelming flashing impact that draws the attention of trophy-class predators. Flat-Side Power & Refined Hydrodynamics Unlike conventional big cranks that rely on bulk and resistance, the Big-M 4.0 generates intense flash and displacement through precise body geometry. The flat sides amplify rolling motion while the low center of gravity maintains stability and tracking accuracy. The short bill design reduces drag, enabling long retrieves with minimal fatigue while preserving depth control and consistent action.

Big-M 4.0

The Next Evolution of the Big Crankbait


The Megabass Big-M 4.0 represents the evolutionary result of decades of big crankbait development. Moving beyond traditional fat-bodied, long-billed deep divers, the Big-M adopts a refined flat-side profile, short lip design and a low center of gravity to achieve a sharper, more dynamic rolling action.



Designed to trace the productive mid-depth zone around 3.5m (11–12ft), it delivers an overwhelming flashing impact that draws the attention of trophy-class predators.



Flat-Side Power & Refined Hydrodynamics


Unlike conventional big cranks that rely on bulk and resistance, the Big-M 4.0 generates intense flash and displacement through precise body geometry. The flat sides amplify rolling motion while the low center of gravity maintains stability and tracking accuracy.



The short bill design reduces drag, enabling long retrieves with minimal fatigue while preserving depth control and consistent action.



Long Casting Performance & Low Resistance Retrieve


Engineered for distance, the Big-M slices through headwinds with exceptional castability. Once in the water, its optimized resistance profile allows anglers to cover large areas efficiently without excessive strain.



This makes it ideal for probing expansive flats, reservoir breaklines and deep structure where big predators stage.



Built for Trophy-Class Predators



  • Pike – Mid-depth structure, offshore weed edges and large reservoirs.

  • Bass – Big fish holding in the 3–4m strike zone.

  • Zander – Active fish positioned on deeper breaklines.

  • Multi-species – Situations requiring strong flash and displacement.



Recommended Techniques



  • Steady retrieve along breaklines

  • Contact retrieve around hard structure

  • Long-distance search pattern cranking

  • Wind-driven bank fishing



Technical Specifications



  • Length: approx. 75 mm

  • Weight: approx. 3/4 oz (21 g)

  • Type: Floating

  • Diving depth: approx. 3.5 m (11–12 ft)

  • Hooks: #2 x 2



Big Profile. Refined Engineering. Trophy Results.


Developed under the guidance of Lake Biwa’s Shinji Sato in collaboration with Yuki Ito, the Big-M 4.0 combines big-bait drawing power with extraordinary engineering precision. A next-generation big crank designed to dramatically increase contact rates with large predators.
