The Shimano World Crank Flash Boost 2-7/8" Floating Lure 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.
