Innovation you've been waiting for. The Lucky Waterproof HDi is the first FULLY WATERPROOF spinner on the market. The HDi is also the first spinner to operate on a Lithium-ion battery, which means it can withstand any weather and provide more consistent power. Same HD body style, but a newly designed (patent pending) module system that has a completely sealed battery box. Module has external remote program button, external charging, and external on/off button. The Waterproof HDi is foam filled for buoyancy, has durable injected molded magnetic wings, and life-like wing print. Complete with HD remote kit, 7 foot stake, and gear bag.
