Thank you for viewing our product m(_ _)m This is 39.FACTORY o(^o^)o We value our customers' feedback and strive to provide, improve, and refine our products daily. ( ^ω^ ) We have discontinued the previous float top and are now offering the newly completed NEW 39.FACTORY float top. Here are the features of the 3rd generation float top: ⭐︎ Following the 2nd generation float top, it can use not only the lithium battery BR435/2B size but also the shorter BR425/2B. ⭐︎ A hard pipe has been added to the float top body, allowing the unstable electrodes to be fixed, preventing problems such as breaking or bending the electrodes. ( ^ω^ ) Along with this, it also prevents lighting failures due to poor contact, which was also a feature of the 2nd generation. The major feature of the 3rd generation float top is that a special cap has been attached to the LED light-emitting part, which protects the LED and improves visibility due to the increased length of the light-emitting part. Please take a look at the product introduction video on YouTube. ( ^ω^ ) Product Introduction (YouTube) NEW Float Top (3rd Generation) https://youtu.be/cU_YFs-FhDw?si=B6FUkiTWGllcEssM The light color of this product is blue. Please use Panasonic BR435/2B or BR425/2B batteries. When night fishing, for various reasons, electric floats drift out to sea, or the electric float's light fails due to poor contact, causing them to break down. I personally experienced this a lot, and every time I had to buy electric floats for around 1000 yen or float tops for around 500 yen at the fishing tackle store. (/ _ ; ) I hated that repetition, and I decided to make them by hand for those who have had the same experience and feel the same way. We would be happy if you would try it once. Thank you very much m(_ _)m Also, since it is handmade, please refrain from purchasing if you have any reservations.
