Get Unlimited MPG

If you’re looking to add some excitement to your next swimming trip, check out an underwater scooter. These electric, handheld scooters will pull you around at a speed of about two to three milers per hour, and are easily controlled. They’re great for zooming around the pool with friends, and even better if you’re a scuba diver.

Using the scooter minimizes exertion, which means your air can last up to 50 percent longer, and the dive time can almost be doubled. With a scooter, you’ll have plenty of time to explore underwater.
