Hollow structure float line – Float type that floats just below the water surface – Specific gravity 1.05 (seawater specific gravity 1.03), which is extremely close to seawater specific gravity – Floats just below the water surface, making it easy to capture points where there are overhanging rocks or sinking roots scattered nearby – Hollow 6 inside the thread The square-shaped hexacave structure provides excellent linearity and line operability.Since it floats just below the water surface, the line to the floating float is straight, so the strike sensitivity at hand is good.The thread is bright yellow for good visibility, so the trajectory Easy to modify
