Shimano Armajoint 190SF Flashboost

The Shimano ARMAJOINT 190SF was developed to make throwing large jointed swimbaits easier and more effective when targeting trophy-class fish. By incorporating Shimano’s exclusive ARMABOOST system, the lure achieves longer, more accurate casts by minimizing air drag and preventing unwanted rotation while in flight. During the cast, the body separates from an internal magnetic connection, allowing the lure to fold into a streamlined profile. Upon water entry, the magnet re-engages, returning the bait to its full swimming configuration.

This smart design delivers a smooth, lifelike action that adapts to a wide range of retrieve speeds. Whether worked quickly or crawled along at a slower pace, the ARMAJOINT typically tracks in a natural S-shaped pattern and maintains its compact profile when paused. Anglers can take advantage of its controlled, slow-rising behavior by incorporating pauses into the retrieve to trigger reaction strikes.

Adding to its appeal, Shimano’s FLASH BOOST technology provides continuous visual attraction by suspending reflective foil on micro-springs inside the lure. This system produces enticing flashes throughout the retrieve and even while the bait is sitting still, closely imitating the look of a wounded baitfish. Built with advanced engineering and purpose-driven design, the ARMAJOINT 190SF helps anglers cast farther, fish smarter, and entice strikes from high-caliber bass.
