This is a specialized lure spinner for small fish, overwhelmingly smaller than commercially available mini-sized spinners. Its features include ease of targeting shallow areas by utilizing its light weight and the lift generated by blade rotation. The included hook is for small fish only, so if you are targeting fish over 20cm, please replace the hook with a thicker one. Although rust prevention treatment has been applied, rust is prone to appear around the holes in the blade where water tends to accumulate. If you flick the blade with your finger or wipe it with a dry cloth after use, it should last longer. Here are the explanations for each model. [0.8g & 1.0g] A well-balanced and easy-to-use model. You can switch between them depending on the depth and current speed of the area you are targeting. [1.2g] A model focused on casting distance, suitable for baitcasting reel users. It requires a slightly faster retrieve speed, but it is also good at inducing reaction bites with fast retrieves as it is less likely to jump out of the water. [0.4g & 0.6g] Models for ultra-shallow and slow retrieve. When fishing downstream, you can keep it near the surface with almost no reeling. The body size is also small, making it particularly effective in tough conditions.
