Key Features & Function
Sound Attraction: They are inserted directly into soft plastic lures (like rubber worms, craws, or tube baits) or attached to fishing rigs. As the lure moves through the water, the small metal ball bearings clack against the glass interior, generating high-frequency clicks that mimic fleeing prey to attract predatory fish.
Sealed Glass Design: The clear glass construction is sealed on both ends to protect the internal bearings while maximizing the crispness of the sound underwater compared to plastic alternatives.
