"Worm217 Zero-Dan" is a high response down shot system with a sinker and hook set directly on the swivel. The structure makes it easy to penetrate the cover, and the bottom detection performance is outstanding. It should be noted that the fall posture, the structure in which the sinker falls straight ahead enables a tighter attack on structures such as piles, synergizes with the action response of the worm, and the difference in pressure situations is It becomes obvious. The "DS-6 Type Stick", which emphasizes pickpocketing, is used as a sinker. A small size has been added to target the approach with bait finesse, expanding the range of fishing with Zero-Dan.
