Sound-Producing Modification Unit A Improved Version ver2 High-quality parts produce good sound quality from the initial movement even with weak tension. I, the Yaen creator, have improved and manufactured this unit, and have repeatedly tested it in actual fishing, so you can use it for a long time with peace of mind. Loud sounds can give squid a sense of discomfort through the sound from the fishing line, and strong tension also quickly wears out the core parts, resulting in many disadvantages. Previously, someone falsely requested photos of my parts and didn't respond, then copied and listed them for sale in mass production, and then complained about others and used photos without permission. What do you all think? It's infuriating. They only copied the shape and used glue without any technical skill, making it difficult to ensure durability. Let's enlarge the differences and take a good look before purchasing. If you remove the spring from the 5-pin photo, it becomes difficult to attach and easily comes off, so two substitute tubes are included as a bonus. If you use them instead of the spring, you can easily remove and reattach it many times.
