Scubadoo is an underwater motorcycle which lets even inexperienced divers bop around under the waves. An integrated tank fills the dome with air, letting the driver breathe (and drink beer) normally while cruising at speeds of up to 2.5 knots. Initial price is recommended to be around $13,000, with the first units available in May. As a scuba diver, I’m torn: in the hands of an unconscientious pilot, the Scubadoo could cause a lot of damage to delicate marine habitats, yet I really want to ride around in the world’s first underwater biker gang punching sharks.
