Lures are the most commonly used types of lures, primarily targeting upper-layer fish, and are the most common in the market. Therefore, our introduction is the most detailed. Its appearance is similar to a slender fish, mimicking the small fish that naturally grow in most waters in Europe and the United States. It is always the target of predatory fish, creating a variety of products. In terms of design, the essential principle of lures is thin and streamlined. These lures not only require realistic shapes and colors, but also must have a low-grade swimming style (do not misunderstand, the low-grade swimming style is the relentless pursuit of lures!). Therefore, there will be small plastic or wooden lips or called pressure plates near the gills of the lure, which are usually extended forward and downward from the area near the gills, maintaining an angle of about 30 to 45 degrees with the mouth. The surface of the lips is flat, and the front edge is close to a semi-circular arc; there are also lures that fix the lips under the mouth of the lure, which are also extended forward and downward, but the angle is different, and the length is also quite inconsistent, with greater changes in shape. Some are gradually wider in front, while others are just the opposite, gradually contracting, even sharp angles. These lips themselves have various types of grooves, with materials mainly plastic or metal plates, and metal lips can usually adjust the angle. The lure itself is floating on the surface of the water, diving under the pressure of the lip plate by retracting the line. The depth is determined by the size, angle, and speed of the retraction of the lips.
