Fast sinking metal jigs. Its centre of gravity is below halfway and can increase the water shearing performance. Fast sinking reduces the drifting time and reach the target water zone rapidly. Based on traditional long and narrow metal jigs, this jig is upgraded into flat, thin and long shape to save effort while fishing. It is recommended to use dark color while sufficient sunlight, light color in cloudy day and luminous in morning and night. One side is glossy with diamond eye to enhance the light reflection and the other side is scale-style to produce multi-angle refraction and attract more fishes.
