Shimano WM Flash Boost

Shimano WM Flash Boost is built for anglers who live and die by the pause—when a jerkbait has to keep working even while it’s sitting still. With Flash Boost foil suspended on micro springs, it throws a lively shimmy of light on slack line and during dead-stops.

Dial it in as a suspending presentation over 4–6ft breaks, shallow flats, and the first outside edge of grass where bass and walleye slide up to feed. Scale Boost adds a composite-pitch hologram that mimics baitfish scale flash through the water column, while Jet Boost’s spring-loaded weight transfer helps you reach the next stretch efficiently without sacrificing balance once it’s in the strike zone. Shimano WM Flash Boost finishes the job with premium split rings and sharp trebles that convert quick hits into solid hookups.

What Sets It Apart

• Keeps fish tracking through pauses, thanks to Flash Boost foil that continues to shimmer even when the bait is still.
• Shows a more natural baitfish profile in clear water, thanks to Scale Boost’s composite-pitch hologram scale pattern.
• Covers more water between targets, thanks to Jet Boost weight transfer that increases casting distance.
• Stays in the strike window longer as a true suspending jerkbait, letting you work slow, repeatable cadence over key depth changes.
• Improves hookup ratio on short strikes, thanks to sticky-sharp treble hooks and stainless steel split rings.
