The 3D Tuna FlapZ is a new fishing tool that is supposed to create a realistic tuna silhouette, it is said to boost the number of blue marlin sightings and bites by 30 to 40 percent.
Fishermen have kept the tool a secret until its popularity grew, and it is now sold by Fish Razr online and in stores. The effectiveness of the tool lies in the billfish brain’s ability to detect and be attracted to a convincing tuna silhouette, as their vision is directed toward the surface to feed on schools of prey.
The 3D Tuna FlapZ simulates this behavior, making it useful in sport-fishing.
