This is a heavyweight tuned model of "Zero-Dan". While maintaining the performance of Zero-Dan, we set it so that aggressive approaches can be handled more comfortably and effortlessly with denser covers such as weed mats.For the sinker, we have adopted the "DS-8 type drop", which does not interfere with hooking even with heavy weights, improves sensitivity, achieves high-level slipping performance, and can withstand rough use. Rotation while considering the thickness of the cover and fall speed draws out more bites. The small size also demonstrates its potential for light rockfish games.
