Shimano Ocea [The key to its appeal is "bubbles"?!] The BUBBLE CHAMBER is a new mechanism where water entering through the intake port on the top of the cup mixes with air inside the body, generating fine bubbles that are then ejected from the nozzle on the back. In addition to the lure's own appeal, the shimmering bubbles left behind as the lure swims enhance its appeal in the water. [The hint is an airplane jet engine?!] The BUBBLE CHAMBER generates more bubbles by taking in more water. Therefore, the cross-section of the intake port is designed to be slightly narrower at the entrance and slightly wider inside. This shape is a technology used in jet engine mouths, adopted to efficiently draw in more air. Applying this technology, we have made efforts to efficiently draw in as much water as possible not only from the front but also around the cup. [Stable flight posture, stable with fewer popping mistakes] Although it has a fixed center of gravity, it is designed with an emphasis on stable flight balance. Furthermore, the buoyancy design keeps the body submerged in water, ensuring the cup is always close to the water's surface. TKM-16-06-02 BC-050020 Ocea OP-120N
