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 consider the possibility of loss and use inexpensive items like sea fireflies when fishing during the day. Miraight and sea fireflies 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 flip up immediately 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 using a Yaen stopper.) ② The large fluorine resin roller provides good smoothness and quietness in the water, eliminating the need to loosen the line to send in the Yaen, making it less likely to give the squid a sense of unease, and 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. There are no barbs (only the third hook has a commercially available barb). ④ When attaching lights to the Yaen, it can be tight, so first put the tube on the Yaen rod, and then wet the Miraight, etc., before pushing it in (the tighter it is, the less likely it is to come off). 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 the squid is caught. 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 body or behind the eyes, which are larger targets. (Caution) ① There is a possibility that the hooks may be distorted, so please correct them yourself. ② No price reductions or bulk sales, please.
