If you’re a keen underwater person, you’ll know that there is only so much that flippers can do to get you going. Meet the cool Tusa SAV-7 Evo Sea Scooter, which is a steup up from the Tokyo-based company’s original SAV-7. Featuring a top speed of 4.2km/h and a maximum depth of 230 feet, the SAV-7 Evo’s newly designed rotational speed adjustment function allows for precise changes to your speed while in motion. This easily activated speed adjustment results in smooth effortless riding and allow for easy synchronization of speed between divers in a variety of geographical areas and varied current conditions. Tusa say it’s easy to vary the propeller’s angle or pitch by three positions, which allows for even more fine-tuning of the scooter’s speed to the individual diver’s needs. Along with a useful LED indicator that lights up to provide you with a guide to remaining battery life, the underwater scooter also boasts saddle wings that let you pull two additional divers.
