The float has an extra long 2mm hollow plastic brush, which is specially extended to support heavy paste baits and provide excellent bite indication, even on subtle lifts and drags. XS stands for extra power. Like all floats in the XS series, this model has been developed to meet the needs of our European anglers who regularly catch big, powerful carp on large commercial sites. Every part of the float is designed to provide maximum strength and durability under pressure.
