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, a feature inherited from the 2nd generation. The major feature of the 3rd generation float top is the addition of a special cap to the LED light-emitting part, which protects the LED and improves visibility due to the longer light-emitting part. Please take a look at the product introduction video on YouTube.

Please use Panasonic BR435/2B or BR425/2B batteries. When night fishing, for various reasons, electric floats often drift out to sea, or the electric lights on the floats fail 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 cycle, and I decided to make them by hand for those who have had the same experience and feel the same way. I would be happy if you could try it once. Thank you very much m(_ _)m Also, since it is handmade, please refrain from purchasing if you have any reservations.
