IPC: A01K81/00
Filed: 2021-07-05
Abstract: Currently, anglers must rely solely on the power and technique using the weight of their fishing rods to cast floats, which makes it difficult for beginners to cast far distances. Even for experts, casting a float further than 200 m is challenging unless the experts possess exceptional strength. To address these issues, a product is proposed that uses air pressure for safety and incorporates a cannon-like design with additional support structures, thereby allowing anyone to use a launcher to cast over 300 m without exerting physical force. The proposed fishing float launcher using an air compressor includes an air tank part for storing air by being connected to the air compressor, a launcher body where the launch occurs, a launch angle adjuster, a trigger, and a fishing rod holder.
