The reason it catches fish is the fat tail.

The sinking pencil Corsair 50 combines outstanding flight distance and high action response thanks to its unique fat tail shape.
It is particularly effective when searching over a wide area or approaching distant pin spots.
The “fishable action” creates natural vibrations by swinging the tail tightly and responsively,
so you can induce bites not only in highly active situations, but also in selective situations where lures with strong vibrations are avoided.

Fat tail design
A unique fat tail design that is fat when viewed from above and below, and slim when viewed from the side.

By designing the tail fat and giving it firm buoyancy,
it is possible to place the weight on the rear of the body without sacrificing action response.
As a result, it achieves both outstanding flight distance and high action response with a stable flying posture.

By designing the sides slim, the vibrations generated during the action are natural.

Low center of gravity molded weight
Low center of gravity molded weight fixed at the optimal position at the bottom of the body.
The lower center of gravity improves action response, and the air chamber inside the body is larger.
