Your next underwater adventure is easier than ever thanks to new products like this one. The S2 is an underwater scooter that is designed to pull swimmers and snorkelers using two electrically powered propellers. The S2 utilizes two 35-watt motors that provide 22 lb of thrust and can pull you down to nearly 100 feet at speeds that top out around 2-3mph. You can keep track of speed, depth, and battery levels using a smartphone app, which also is equipped with parental control for parents to remotely control the scooter while in use in a swimming pool. The scooter is also incredibly light at just under 6 pounds, making it an easy addition to your vacation gear this summer.
