The O'Brien Combo Trainer Rope is great for teaching both adults and children the perfect form needed to get up on a pair of combo skis. The special handle is designed to keep both skis parallel while you're being pulled out of the water. The handle will slide off the skis once the skier is out of the water. 70' detachable mainline is constructed from 16-strand, 40-filament poly rope. Rope features an internal layer of foam that keeps it on the surface for easier visibility. Combo trainer handle measures 5' long.
