Shimano Armajoint Flash Boost 190SF Lure

Cast a full-size 190mm swimbait further and more accurately with the Shimano Armajoint Flash Boost 190SF, built to tempt big bait-eating predators with a lifelike swimming action, flash and realistic finish.

The Shimano Armajoint Flash Boost 190SF Lure is a 190mm, 53g jointed swimbait designed for anglers targeting large predatory fish. Shimano's Arma Boost hinge system allows the lure to fold during the cast, improving its flight stability and helping anglers reach fish that may be difficult to approach with a large-profile lure.

Once in the water, the Armajoint combines its jointed swimming action with Flash Boost, which continues producing fish-attracting flash even when the lure is paused. Scale Boost adds a realistic external finish, while the slow-floating design gives anglers control over retrieve speed and pauses when working likely holding areas.

Key Benefits

• Arma Boost Technology – Allows the jointed body to fold during the cast, with Shimano stating casting distance can be increased by up to 40% while improving flight stability and accuracy.
• Flash Boost – Produces continuous internal flash during the retrieve and even while paused, helping maintain visual attraction around following fish.
• Scale Boost Finish – Creates a highly realistic scale appearance for a more natural baitfish presentation.
• Large Jointed Profile – The 190mm swimbait profile is designed to appeal to larger bait-eating predators.
• Spare Soft PVC Tail – Includes a replacement tail to keep the lure ready for use if the original becomes damaged.

Expert Advice

The Armajoint 190SF is best treated as a big-fish swimbait rather than something that needs to be retrieved quickly on every cast. Start with a controlled retrieve that lets the jointed body work naturally, then experiment with pauses to take advantage of Flash Boost continuing to flash while the lure slows or stops. When casting a 53g lure, make sure your rod, reel, line and leader are appropriately rated for the lure weight and the size of fish you expect to encounter. Focus casts around structure, edges and areas where larger predators are actively hunting baitfish.

Frequently Asked Questions

What type of lure is the Shimano Armajoint Flash Boost 190SF?

It is a 190mm, 53g slow-floating jointed swimbait designed to imitate a substantial baitfish and attract larger predatory fish. Its hinged construction provides both swimming action in the water and Shimano's Arma Boost casting function.

How does Arma Boost help when casting this swimbait?

The Arma Boost hinge allows the lure to fold in half during the cast. This reduces the problems normally associated with casting a large jointed swimbait, improving flight stability and accuracy. Shimano states the technology can increase casting distance by up to 40%.

What does Flash Boost do on the Shimano Armajoint?

Flash Boost is designed to continuously produce fish-attracting flash inside the lure. Importantly, it can keep flashing when the fishing lure is paused, giving anglers another visual trigger when a predator follows the swimbait but does not immediately strike.

Does the Shimano Armajoint 190SF come with hooks and a spare tail?

Yes. The lure is supplied with twin treble hooks in #1 and rear #2 sizes, as well as a spare soft PVC tail. This gives you a replacement tail if the fitted one becomes damaged during fishing.
