Shimano's BOOST CONCEPT technology triumphs in the depths with the introduction of World Crank 73F FLASH BOOST, a mid-depth crankbait designed with a distinct action to elicit bites from trophy fish. Featuring Shimano's proprietary FLASH BOOST technology — a foil suspended on micro springs within the body of the lure — the World Crank emits a continuous flash that mimics a wounded baitfish, even when paused. The lure's large front lip creates an aggressive swimming action that reaches depths of 10 to 12 feet with a constant retrieve. FLASH BOOST technology proves deadly during the retrieve when attacking deep strikes zones. When paused, the lure slowly rises with a wobble that activates FLASH BOOST to resemble the quivering action of a wounded baitfish. The WC-73F FB also capitalizes on Shimano's JET BOOST technology to increase casting distance, enabling an angler to work the water column more efficiently. SCALE BOOST Technology utilizes composite-pitch holograms to provide the WC-73F FB with lifelike scale patterns to fool even the wariest of trophy bass. Dive deep with Shimano's BOOST CONCEPT, fish the World Crank FB.
