The Megabass Vibration-X Smatra (Bone Knocker) a compact profiled, 64.5cm, 14.1grams (1/2oz), sinking, vibration, lipless crankbait, fishing lure that is designed for midwater search bait action. The lure is designed with a wide forehead and a lug point positioned at the highest point on its dorsal section that ensures that the Vibration-X Smatra (Bone Knocker) will catch water and produce intense vibration as it is being retrieved. To enhance its appeal, the Vibration-X Smatra (Bone Knocker), comes equipped with a single large internal rattler (as opposed to the Rattle In version which comes with several small internal rattlers that have a higher pitch metallic knocking sound) that emit a high pitch denser / bony sounding rattle that is guaranteed to attract the attention and induce a reaction strike from its intended target. Dorsal and pectoral chine edges have been slight rounded, which ensures that the lure will produce a longer roll to expose more of its flanks to reflect light. To counter this accentuated rolling action, Megabass have incorporated a crescent-shaped tungsten balancer at its lowest point in its belly to ensure stability and to keep the lure on an even keel. The Vibration-X Smatra (Bone Knocker) is best worked on a fast retrieve to produce intense rattle and vibration, which makes its an ideal lure to be used as a search bait to comb wide sections of water. The recommended line rating for this lure is 8-16lbs (for fluorocarbon line) on a fast actioned rod rated at 10-20lbs.
