Although it was originally a minnow for salt water, the ``Wavey'' gained the trust of many trout anglers as the originator of the sinking minnow twitching method. The reason for this is the highly appealing flutter hit by twitch, and the high accuracy performance and distance produced by the stable flight attitude. In today's world of heavy sinking minnows, Wavy belongs to a relatively light category, but it can also be said to be a sinking minnow that can be used in any field. For example, during the summer dry season, they can swim in shallow streams with no depth.
