Hydrodynamic sinker

Hydrodynamic downrigger: this is an important component attached to the trolling line. In our catalog, you'll find them in various sizes, with and without a fin. The hydrodynamic downrigger allows the line to sink to depth, thus providing a decisive action. The materials used to make the hydrodynamic downrigger allow the bait to both "travel" to the desired depth and to rise to the surface upon a bite, maximizing fishing ease.
