Shimano Armajoint 190SF Flash Boost

The Shimano Armajoint 190SF Flash Boost is built to make big, multi-joint swimbaits easier to cast with real control. Shimano’s ARMA BOOST system folds the body into a compact shape during the cast, cutting air resistance and reducing the spin that robs distance and accuracy.

Once it hits the water, the body reengages for a smooth, natural swim with slow-floating action, cruising in a clean S-pattern. The fold keeps it from flaring out on the stop, so your pauses stay tight and believable around shallow cover. Shimano Armajoint 190SF Flash Boost also uses FLASH BOOST, constantly kicking out baitfish-like flash on the retrieve and on the pause to sell that injured profile when the fish follow but won’t commit.

When & Where It Shines

• Reaches more targets with better accuracy, thanks to ARMA BOOST folding the lure into a compact casting posture.
• Keeps followers engaged through the pause, thanks to FLASH BOOST emitting flash even when the bait isn’t moving.
• Maintains a natural glide without blowing out on stop-and-go retrieves, thanks to the body fold that prevents flaring.
• Covers skinny water efficiently as a shallow-running bass swimbait, with an S-swim you can speed up or slow down to match mood.
• Stays easy to fish around weed tops, docks, and shoreline breaks, thanks to a slow-floating rise that helps avoid snagging after the pause.
