This is a pretty cool device that I think I remember when I was a kid, on something like Voyage To The Bottom Of The SEA. It’s called the Reef-Rider Seascooter, and it can get up to about 2.2 mph underwater. It is very lightweight, and compact with safety features such as a protective grille, and auto shut off. Kids can even use it (8 years and up). It will operate up to a depth of 3 meters, and a full charge will last about 50 minutes. Cost is around $200.
