RV-BUG is a sinking type "sinking insect lure" that overturns the conventional wisdom that insect lures are on the surface of the water. High specific gravity material and unique parts are placed to invite underwater. With no sinker, while falling horizontally, the presence is naturally appealed from 5 pairs of legs (legs) with slight waves. Furthermore, the small shad tail arranged like a beard emits sharp waves even when pulled sideways. Imitate not only aquatic insects but also shrimp with down shots and Carolina rigs. One of the attractions is the ease of use that allows the angler to tune up as intended by cutting the legs and adjusting the volume.
