The Salty Core Tubes from KEITECH are salted tubes impregnated with squid aroma. The special thing is that these tubes are not hollow on the inside, but filled with an extremely salted rubber compound. On the outside they are surrounded by a lightly salted rubber compound, so they are generally beautiful and flexible yet durable, resulting in a very high bait weight of almost 8g, as well as very good sinking behavior, even without additional weights. This way, the Salty Core Tubes can be fished optimally weightlessly and thus enable a very natural presentation. The Keitech tubes can be used regularly, but fringes work very well at first (back slide rig) With this type of bait, the salty core tubes of the fisherman dive away when the line is loose, so that you can optimally slide your bait under jetties or water lilies. Keitech Tubes are also very useful on the Texas / Carolina Rig or Jig Head iger rubber bait for perch, zander and pike!
