MK54 series Big Vibe lipless crankbaits weigh 10 gr and are 80mm long, with 2 black nickel coated size 6 trebles.
They are designed to attract reaction strikes. When jigging vertically let the lure hit bottom, then raise it a small distance before beginning your action, keeping it above the weed bed and in the most productive strike zone where the internal rattles can produce their low level sound, attracting predatory fish.
A great performer across a wide range of River and Reef species.
