Sound Modification Unit A Improved Version ver2 Disassembly Special Tool SET All stainless steel (rust-resistant) can be disassembled by hand. By installing this part, a sound is produced when the handle is rotated in reverse, and appropriate tension is applied (adjustable), preventing backlash. Installation can be done with the original screws in about 10 minutes. We provide support for easy installation! We also adjust the initial tension. Just install it after purchase and you're good to go. If you're unsure, there's a handwritten diagram and written instructions, so you'll be fine. Good parts produce good sound quality from the start, even with weak tension. As the author of the Yaen (fishing lure), I have improved and produced this, and have repeated field tests, so it's safe for long-term use. Loud sounds can give squid a sense of discomfort from the sound of the line, and strong tension also wears out the core of the parts quickly, resulting in many disadvantages. I was the first to come up with and improve the parts and put them on sale. I'm explaining the facts because I'm annoyed by the unauthorized use of photos of products I don't have, complaints, excuses, and sneaky methods. I and another person were asked to upload clear photos at night, but there was no response. One day, a copy was put on sale in a local factory for the purpose of sales. Only the shape is copied, and the spring movement part is fixed with glue. They don't understand the meaning of the spring (lol) Do you trust liars and people who make excuses? Please take a good look at the differences in the springs. I'm selling these products while considering various things from the buyer's perspective, especially the price. If you remove the spring from the pin in photo 5, it becomes difficult to attach and it stretches and comes off easily, so two substitute tubes are included as a bonus. If you use them instead of the spring, you can easily remove and reattach them many times.
