The Z-Man ChatterBait JackHammer is a bladed swim jig engineered for freshwater bass fishing. Built to produce instant, high-vibration action, the JackHammer's low-center-of-gravity head and patented ChatterBlade make it ideal for skipping under docks and provoking reaction strikes. Z-Man's design combines tournament-proven mechanics with premium components for reliable performance. Key Features Patented ChatterBlade: Ultra-thin stainless steel blade starts vibrating immediately to imitate a frantic baitfish and draw strikes at all retrieve speeds. Low Center of Gravity Head: Flat, grooved bottom and weight-forward profile help the bait skip beneath overhangs and maintain a true track. Premium Components: Stout Gamakatsu heavy-wire flipping hook and double-wire trailer keeper secure soft-plastic trailers and increase hook-up ratios. Realistic Presentation: Hand-tied silicone skirts and color-matched paint schemes deliver lifelike action and durability in heavy cover. Anglers choose the Z-Man JackHammer for reliable, tournament-level performance when targeting bass around structure, docks, and shallow weeds. It fishes well with a rip-and-stop technique or a steady retrieve, and pairs perfectly with a variety of soft plastic trailers (paddle tails, tube trailers, grub tails) to add profile and action. Z-Man offers a range of sizes and colors to match forage and water conditions. Specifications: lure length ~4.5" and lure weight 1/2 oz. Packaged dimensions are estimated at 5.25" L × 3.00" W × 1.00" H with packaged weight approximately 2.08 oz (packaging varies by retailer). Compatible with common bass rigs and trailer styles.
