The Keitech Super Round Tungsten Jig Heads are high performance, professional-grade lures from Japan, designed to give anglers an edge in any tournament. The popular round head with an extra slender collar never tears your worms and keeps various soft plastic baits secure. The hooks are designed with a specific bend, which increases strength and hook ups. Tungsten is significantly harder and denser than its lead counterparts, which enables the rounded head to be smaller - for less fouling. The hardness of the tungsten also enables the angler to ‘feel' the bottom better and keep the bait in the strike zone more effectively. Tungsten is also better for the fisheries than lead - helping to protect our lakes and rivers.
