Radar Firebolt 46 Waterskis w/ Adj Horseshoe Bindings are for children just learning the joys of water skiing. The Firebolt 46 Waterski is suited for children weighing up to 80 pounds. The horseshoe style bindings are adjustable which is helpful because children grow quickly and this will help the Radar Firebolt 46 skis to be usable for your family even longer. Because children aren''t always confident in the water, these water skis feature a stabilizer bar. However once your child gains confidence and skill, he or she will probably not want this bar in place, and it is designed to be removable.
