The latest thing in sinkers for trolling! Conceived by Gianni Zanaboni, after years of design work, it is now produced in a 450gr model. It's easy to position on the line and equally easy to release, without damaging the line in any way (abrasions, twisting etc). It's highly aerodynamic shape and two wings stabilize its movement in the water, ensuring perfect sinking of the line. It offers almost complete stability with no wake, which makes J'Tuna suitable for use with all types of bait.
