The unique low profile will blend in with any lake bed and prevents damage to line whilst elastic locks weight firmly in place. The weight is attached simply by stretching a piece of the elastic and placing into the slot, once located it can be moved by moistening the line and gently sliding. Designed for balancing pop-ups, pinning down the last few feet of mainline as an alternative to leadcore and for keeping hook links tight to the bottom. Finished in non-reflective black and non-toxic material.
