The Mascle Deep 4+ from ILLEX are equipped with a 'weight transfer system' to enable long casts. The long and extra reinforced blade is designed to knock on stones and other obstacles. If he gets stuck on a stone, he normally swims upwards on the loose leash against the running direction and thus becomes free again on its own. Seiji has equipped the Mascle Deep with 80% wobbling and 20% rolling and despite the long blade, he does not pull too much on the line when fishing in.
