The XTR Fast Change PopUp is a brilliant pop-up weight system that allows the counter weight to be altered in seconds. 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 lead core and for keeping hook links tight to the bottom. Finished in non-reflective black and non-toxic material.
