Seewolf Knaller are used with extra high weight to effectively sense and "knock off" the bottom, as catfish (stonefish) react strongly to these knocking sounds. The heavy construction keeps the bait close to the bottom even when fishing in currents or deeper, making it possible to present the bait exactly where the fish is.

The bait is equipped with two hooks, which gives a clear advantage when fishing for catfish. If the bait should be attacked by crabs or if a strike is missed, there is still a second hook ready. This increases the chances of a safe hooking and reduces the risk of dropped fish - you simply always have an extra "iron in the fire".
