About this piece
The Shimano Ocea Head Dip 140F Flash Boost is a hard-bodied floating plug designed specifically for targeting yellowfin tuna in Sagami Bay. Its low-buoyancy construction keeps the lure mostly submerged, allowing the Flash Boost feature to continuously flash even during pauses, while the larger hook setup provides confidence when fighting big fish.
