The Straight Tail Worms are surprisingly effective, especially during the warmer months when fish pressure and boat traffic are at their peak. Roboworm uses state-of-the-art robotic technology (hence the name Robo-worm) to create consistent, well-defined colors every time. It also allows them to create unique color combinations, usually only found in 'hand poured' worms. The super soft plastic Strait Tail Worms end up having a very sensitive, alluring action complete with a Salt Release System that provides a burst of salt when a fish bites ' causing them to hold on longer for solid hooksets.
