Sublue's WhiteShark MixPro, in black gold, allows you to effortlessly explore the waters by simply holding on with your hands. The WhiteShark MixPro is a compact dual propeller underwater scooter that will pull you along in various underwater activities at up to four miles per hour (about six feet per second). It runs for up to 60 minutes on the included battery, which can be replaced with a spare or recharged in about two hours. Use the MixPro for snorkeling, scuba diving, free diving, or even in a swimming pool. Attached is a buoyancy tank that ensures the MixPro won't go deeper than about 16 feet, but more experienced divers can remove this tank and dive down to 131 feet.
