Users will also appreciate the Dolphin's lightweight design, which weighs a mere 12 pounds and is easy to carry in one hand. And should you want to dive down a few feet while skin-diving, the Dolphin can handle that, too, with a maximum depth rating of 15.5 feet. Other details include waterproof circuitry that protects against accidental flooding and a run time of up 1.5 hours per charge with normal use. The scooter, which is designed for children or adults 8 years and older, is backed by a 180-day warranty.
Not really a scooter, more like a big fan that you just hang on to. In any case it is really cool, and takes the effort out of actually moving your arms to dive. Another point for inventions by laziness.
