Shimano designed the ARMAJOINT 190SF to solve the challenges of casting a big jointed swimbait in search of trophy fish. Lure engineers leverage Shimano's proprietary ARMA BOOST technology to significantly increase casting distance and accuracy by reducing unnecessary air resistance and the chances of the lure spinning during flight. As the angler casts the lure, ARMA BOOST technology facilitates the lure to disconnect from an internal magnet and forces the body to fold into its compact shape. Once the lure hits the water, the lure's body reengages with the magnet to create a smooth and natural swimming action. The ARMAJOINT 190SF is a versatile lure that can be retrieved fast or slow, enabling anglers to vary their retrieve depending on the situation. The ARMAJOINT will normally swim in an S-pattern, but the bait will not flare out when stopped due to the fold in its body. Anglers can slow down the receive and pause the ARMAJOINT 190SF to capitalize on the lure's natural slow-rising action. ARMAJOINT also features Shimano's proprietary FLASH BOOST technology that constantly emits a fish-attracting flash during the retrieve — even on the pause — by suspending reflective foil on micro springs to mimic the flashing behavior of an injured baitfish. Designed with purpose by leveraging innovation and technology, the ARMAJOINT 190SF improves angler performance while drawing strikes from tournament-winning bass.

• ARMABOOST: Shimano leverages its ARMABOOST technology to increase a lure's casting distance by folding the lure into a compact shape, reducing air resistance and minimizing the chances of the lure spinning during flight. As the angler casts the lure, ARMABOOST technology enables the lure to disconnect from an internal magnet that allows the body to fold into its compact shape. Once the lure hits the water, the body reengages with the magnet to create a smooth and natural swimming action — a characteristic of premium jointed swimbaits.
• FLASH BOOST: Mirror plate continues to reflect. Unique structure. Shimano engineered its innovative and revolutionary FLASH BOOST technology to constantly emit a fish-attracting flash during the retrieve, even on the pause. FLASH BOOST technology suspends reflective foil on micro springs within the clear section of the lure body and provides an action designed to mimic the movements and flashing behavior of an injured baitfish. Entice bites from even the most finicky of fish with FLASH BOOST technology.
• SCALE BOOST: Shimano designed SCALE BOOST lure technology with its exclusive composite-pitch holograms that mimic realistic patterns of baitfish scales. Compared to lures with single-pitch holograms, SCALE BOOST technology capitalizes on composite-pitch holograms to increase the amount and complexity of light reflected through the water. The result: A lineup of lures featuring the realistic baitfish patterns of SCALE BOOST lure technology that will draw aggressive bites from trophy fish.
