Shimano WD Flash Boost

Shimano WD Flash Boost is a compact deep diver built for times when fish want a smaller meal but still need a hard trigger. It gets down efficiently, then holds the zone with a tight, controlled posture that stays true through snaps and pauses.

Flash Boost adds a high-visibility flicker on the retrieve and keeps flashing on the pause, selling that wounded-baitfish look that pulls strikes from wary bass. Work it as a rip-and-stop over points, along deeper weed edges, or across rock transitions—then let it hang in front of suspending fish that won’t chase far. Shimano WD Flash Boost shines when you need reach without an oversized profile, especially in clear water or post-front conditions.

When & Where It Shines

• Keeps fish engaged during dead-sticks, thanks to Flash Boost continuing to throw light on the pause.
• Gets you to deeper suspending fish without up-sizing, thanks to its deep-diving design and compact body.
• Improves hookup confidence on quick reaction bites, thanks to two sticky-sharp treble hooks.
• Lets you dial in a true suspending jerkbait cadence—snap, pause, repeat—when fish want a bait that hangs in their face.
• Adds an extra trigger on pressured bites, thanks to Shimano WD Flash Boost combining flash on the move with flash at rest.
