This is a modified version of the traditional swing-type Yaen (squid hook) with a structure that allows for the attachment of items like Miraight (glow sticks). Since the balance is affected if nothing is attached, please use inexpensive Umihotaru (sea firefly) or similar items when fishing during the day, considering the possibility of loss. Miraight and Umihotaru are not included, so please purchase and attach them yourself (a tube that fits both will be included). (This Yaen may fail if used with the conventional Yaen methods, so both beginners and veterans should be sure to read the profile.) Weight: Approximately 13g, Total Length: 36cm Made of 1.2mm super-hard stainless steel For horse mackerel around 15cm (Features of the Fluorine Roller Swing Yaen) ① Even if you can't see the Yaen reaching the squid, it will immediately flip up upon arrival. The advantage is that it increases the probability of hooking the squid before it can escape, even before it drops the head of the horse mackerel, making it easier for beginners to fish (provided the squid is holding the bait vertically). Upon reaching the squid, the structure allows only the main body of the Yaen (the first support point) to swing up (jump forward), leaving the second and third support points on the line. Unlike conventional flipping, there is no loss of lifting the hook, and the forward speed, the weight of the Yaen, and the water pressure when reeling in all contribute to the flipping force. (Once the Yaen reaches the squid, you will reel it in while maintaining the flipped-up state by loosening the line with a three-point Yaen stopper.) ② The large fluorine resin roller provides good smoothness and quietness in the water, making it less likely to give the squid a sense of discomfort, as there is no need to loosen the line to send in the Yaen, which is good for long-distance hooking. ③ The hooks are self-made from super-hard stainless steel, designed to catch a wide range and be sharp and deep. They are barbless (only the third-stage hook has a commercially available barb). ④ When attaching lights to the Yaen, it can be tight, so first insert the tube onto the Yaen rod, and then push in the Miraight, etc., after wetting them (the tighter fit prevents them from falling out). ⑤ Even without a Yaen stopper, the Yaen will instantly pierce the hook tip into the squid's body upon arrival, so there is no need to set the hook, and you can still catch squid. General Yaen hooks are designed to catch on the squid's legs when setting the hook or when the horse mackerel is released, but this Yaen is designed to pierce the larger body or behind the eyes. (Notes) ① There is a possibility of distortion in the hooks, so please correct them yourself. ② No price reductions or bulk sales, please.
