Product Details and Uses

Madness Madfin 6″ – 15cm: The Bewitching Finesse Eel

The Madness Madfin 6″ is a specialized, flat-sided pintail soft plastic designed for maximum mobility and visual deception. At Gerry’s Fishing, we highly recommend the Madfin for targeting “educated” predators in both salt and fresh water. Its slender, sandeel-like profile and ribbed sides allow it to glide through the water with a “bewitching” and subtle swimming action that triggers strikes even in highly pressured areas.

Constructed from a remarkably soft and flexible Japanese compound, the Madfin is engineered to react to the slightest rod tip movements. It is a “finesse” tool through and through, designed to mimic a fleeing or distressed prey fish like a sandeel, sprat, or small mullet with incredible realism.


Technical Design & Bewitching Action

  • Ribbed Flat-Sided Body: The flat sides and subtle ribbing create a unique vibrational signature and visual “flicker” that mimics the flash of a thin baitfish.

  • High-Mobility Tail: The fine pintail responds to the smallest water currents or rod twitches, providing a natural undulation that is far more subtle than a standard paddle tail.

  • Exceptional Suppleness: This is often cited as one of the softest lures on the market. This flexibility allows fish to inhale the lure with zero resistance, leading to a near-perfect hook-up rate.

  • Sandeel Profile: The 15cm (6-inch) length is the “magic size” for coastal bass and estuary predators, perfectly matching the silhouette of their primary prey.

Best Fishing Techniques

The 10g weight and flexible design make it a versatile performer. The Gerry’s team suggests:

  • “Scratching” the Bottom: Fish it on a short-shank jig head and bounce it along the substrate. The short shank allows the body maximum freedom to move and undulate as it “scratches” through the sand or gravel.

  • Escaping Prey Animation: Use long, wide pulls with the rod to lift the lure through the water column, followed by a controlled fall. This mimics a baitfish attempting to flee upward to safety.

  • Weedless Shore Tactics: Rig it on a 5/0 weighted or unweighted offset hook (like the Owner TwistLOCK) to search through kelp gullies. Because it is a lighter lure for its size, adding a few lead wraps to the hook can help it reach the strike zone in tidal currents.

  • Vertical Boat Finesse: A devastating choice for pollack and zander. The subtle pintail vibrates even when the lure is held stationary in a light current, making it ideal for vertical presentations in deep water.

Gerry’s Verdict:

The Madness Madfin 6″ is a professional-grade finesse lure that prioritizes realism and mobility over aggressive vibration. It is a “bass-killer” in the summer months and a refined tool for any angler who needs to trick fish in clear water. With 4 lures per pack, it is a high-quality addition to your finesse arsenal
