The Spro rubber fish system offers excellent flexibility for spin fishing for pike, zander, and perch, as anglers can quickly adapt to various fishing conditions. The softbait spirals are made of stainless steel and can be easily screwed into the rubber fish. A stinger treble can also be mounted on the eyelet, which is then fixed in the last third of the rubber lure. Additionally, separately available lead heads in different weights can be mounted on the spiral. If the lead weight of the lure needs to be changed, simply remove the ball weight and attach a different weight. This process is not only quick and easy but also protects the rubber lures, as there is no need to constantly change the entire jig hook. The Spro softbait spiral screw heads for rubber fish are very well suited for rubber fish fishing for pike, zander, and perch.
