Unused item. Rubber swivel Length: 1m Thickness: 4mm YAMASHITA Shock absorber Rubber cushion Role of the rubber swivel Prevents line breakage: Absorbs the impact of a fish's sudden pull, preventing the line from breaking. Reduces dropped fish: Softens the impact when a large fish is hooked, preventing the fish from escaping due to a torn mouth. Promotes follow-up bites: By using a short rubber swivel, the impact after a fish is hooked can be used to effectively scatter chum, aiming for follow-up bites. Prevents rig tangling: The physical distance from the sinker allows the rig to drift more easily with the current, making it less prone to tangling. Rubber swivels are particularly effective when fishing for fish with weak mouths or strong pulls.
