Lightweight Modification Unit B 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, so you only need to install it after purchase. 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 creator of the Yaen, I have improved and repeatedly tested this in actual fishing, so it's safe for long-term use. Loud sounds can give squid a sense of discomfort due to the sound from the line, and strong tension also wears out the core of the parts quickly, leading to many disadvantages. I was the first to propose and improve these parts and put them on sale. I will explain the facts because I am annoyed by the unauthorized use of photos of products I don't have, complaints, excuses, and sneaky methods. I and another person were asked late at night to upload clear photos, 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 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 am selling these products while considering various factors 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 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.
