Ace Sinking Rig Tube is designed to eliminate tangles during the cast, anti tangle tubing also helps protect the flanks of the fish by preventing the line from coming into contact during the fight and possibly dislodging any scales! Easy to thread, and featuring a non-reflective matt finish, this sinking tube is available in Silt, Gravel and Weed options that were created to blend in with the lake bed to avoid spooking any fish in the vicinity of your rig & bait.
