At Gerry’s Fishing, the Megabass Zonk 120 SW is legendary among shore anglers for its extreme casting performance and unique acoustic signature. This 120mm, 20g sinking minnow is a technical masterpiece designed for “prospecting” large areas of water. Its most striking feature is the thin, flexible fiberglass bib (lip), which provides a sharper, more immediate contact with the water than traditional plastic lips, resulting in an incredibly tight and high-frequency rolling action.
The Zonk 120 SW is also famous for the “Sound Channel” on its back. As the lure moves through the water, this channel creates specific turbulence and a “hissing” sound that mimics the vibration of a fast-moving baitfish. This combination of visual flash, tight vibration, and acoustic attraction makes it a “must-have” for Bass anglers who need to reach distant feeding fish in choppy or deep water.

The Megabass Zonk 120 SW is a tactical precision tool for long-distance shore fishing:
Ballistic Casting Accuracy: The Zonk 120 features a sophisticated internal weight transfer system. On the cast, the weights shift to the rear, allowing the lure to fly straight and true like a dart, even in heavy headwinds.
Fiberglass Bib Technology: Unlike rigid plastic lips, the fiberglass bib is thin and resilient. It allows the lure to “bite” the water instantly and maintain a consistent, tight roll even at very high retrieve speeds or in turbulent currents.
Acoustic Sound Channel: The longitudinal groove on the back of the lure is a classic Megabass innovation. By creating micro-turbulence and a subtle “hiss,” it adds a sensory layer of attraction that helps predators locate the lure in murky or “fizzy” water.
Versatile Depth Control: As a sinking lure, the Zonk 120 allows you to “count down” to your desired depth. This makes it ideal for fishing over deep ledges or through the middle of the water column where Bass may be suspended.
Specimen Hardware: It is equipped with three razor-sharp saltwater trebles, ensuring a high hook-up rate when fish strike at high speed or “nip” from the side.
Gerry’s Pro Tip: The Zonk 120 SW is a “Search” lure. Because it casts so far and has such a tight, high-vibration action, it’s perfect for covering ground quickly. Try a “power-retrieve” with occasional pauses—the lure will sink slowly on the pause, often triggering a strike from a Bass that has been following the high-speed vibration
