The Free Slide of the JUMBO series, by the Greek company TechnoFISH, features a round shape that allows them to sink naturally. Their unique characteristic is that the lures are not tied to the line but move freely along it (Free Slide). The head sinks first, followed by the Assist Hooks and the bait. As the lure descends, the tentacles and bait are distanced from the lure and sink at a slower rate. Then, once the lure settles on the bottom, the rig is retrieved, which starts to approach the lure, adding extra movement and triggering predator reactions.
