Weighted casting spinners, such as the Metric Pro Spinner, Bang-Tail and Shyster produce a completely different pattern of underwater vibrations than spoons because the blade of these lures revolves around a fixed shaft. If a line attachment device such as a barrel swivel is not all ready on the spinner, you will need to attach a snap swivel to the eye of the spinner. Spinners, because of their action, should be used with a snap swivel, the ball-bearing type being the absolute best. One spinner, the Shyster does not require an additional swivel as it features a keel-type wire shaft which helps prevent the lure from revolving or twisting. Your line may be tied directly to its eyelet if you choose.
All spinners produce sonic vibrations under water.
Some produce more than others, depending on the shape of the blade and how it is attached to the shaft. Because the blade revolves directly on the shaft, the in-line Tiger Tail produces maximum frequency sonic vibrations, thereby resulting in an extremely effective lure. In addition to its sonic appeal, this spinner also is easier to cast because the blade lies tight to the shaft. In lake fishing with either spoons or spinners, it is important to recognize that fish will be at different levels, depending on the location of food sources, the time of day, degree of sunlight penetration in the water and the level of the thermocline. River fish, on the other hand, generally tend to be found close to the bottom unless a major insect hatch draws them to the surface.
