Convenience: Because it comes pre-rigged and ready to load bait, you save time during setup.
Enhanced attraction: The sponge + scented bait combo helps attract fish by scent/chemical trail rather than just visual.
Better retention: The body design helps the bait stay on the rig rather than wash off immediately, giving fish more time to bite.
Versatility: Can be used in a variety of conditions with different dip baits or scented baits, for different species.
