This listing is for a set of 【21g X 4】 pieces. 【21g】 Heavy weight, balanced type. Both 18g and 21g are used not only for horse mackerel (aji) fishing, but also for various other fish species and fishing styles, such as surf fishing with long rods for long-distance casting to catch Japanese whiting (kiss), flatfish (hirame), sea bream (madai), etc., and boat casting for bottom fish. The 21g version is designed to maintain a more horizontal posture in the water, slowing the descent with the body's resistance and reducing the drag during retrieval. It's a long-slide specification, but since it's heavy, it might sink faster than it slides. For those who want maximum distance, we can create a long-cast specification separately, so please inquire. For 18/21g, the load during casting is also significant, so we recommend a cushion rubber with a small hole and a firm material. It's okay if the rubber is embedded in the swivel, but please use one where the end of the Carolina rig doesn't touch the bottom or get buried. Recommended products are the black type made with carbon mix. Tsuriken Uki Cushion T type or Kizakura Hishigata Uki Cushion are recommended. This is the PeeCaro Carolina sinker, made as a hobby. You can use it for light games such as Ajing (horse mackerel fishing) and Mebaring (rockfish fishing). Carolina rigs have issues like the tail bending, breaking, or getting cut. This Carolina sinker was created to solve these problems. The reinforced tail pipe creates a stable flight and sinking posture, producing outstanding long-distance casting performance. It excels at range keeping and won't budge with a little jerking. We've also received reviews that it reduces line tangles. It's easy to detect the bottom and understand the line tension in the mid-water, so it's also recommended for beginners. If you wish to purchase more or purchase with other items, please contact us. We will handle it with a dedicated listing. Up to 13.5g @ 300 yen, 18g or more @ 350 yen. Shipping via Nekopos (Japanese postal service). The unique field environment of the Uwa Sea. To go further. To catch big horse mackerel lurking in deeper ranges. That is the goal of this Carolina rig. #Ajing #Mebaring #Float #KissGame #HeavyCaro #MCaro #GigaAji #AjiRingerPRO #ShakuAjiRinger #Keitech #EasyShaker
