You can upgrade to a multi-function carabiner for an additional ¥40 per item. Please comment before purchasing if you wish to do so. With 12 LEDs, it has considerable illuminating power and is more than sufficient for fishing. The blacklight itself has also been modified to function as a line breaker. It's a great value item that serves two purposes. *Uses 3 AAA batteries. Batteries are not included. ① Blacklight For mebaring, ajing, egging, etc., you often use luminescent lures, but do you illuminate them with a headlamp? You'll understand when you use it, but headlamp light has low UV intensity, resulting in shorter luminescence duration and less light output. In contrast, blacklight has more UV rays, significantly increasing luminescence and duration. Luminescence fades over time and needs to be repeated, so we recommend using a portable blacklight for sustained glow. ② Line Breaker Snags are unavoidable no matter how hard you try, but when you can't retrieve your lure, you may need to decide to cut the line. Many people cut the line by pulling the rod or by wrapping the line around their hands. However, pulling the rod can put a great deal of stress on the rod and reel, potentially leading to damage in the worst-case scenario. Also, wrapping the line around your hands to cut it can result in cuts to your hands. When you decide to cut the line due to a snag, using a dedicated tool (line breaker) can reduce these risks to almost zero. Additionally, it can be used to tighten the knot when joining PE line and leader to increase knot strength. I also have many other self-made convenient tools for sale.
