Image of 23 from Cayago Magnum: turning Navy Seals into dolphins?

October 10, 2007 The Seabob electric underwater propulsion device captured our imagination earlier in the year, acting like a 20kmh powered bodyboard and allowing users to dart along coral reefs and the ocean floor like they were born with fins. We’ve since discovered that the company has now produced a souped up version called the Cayago Magnum with 2½ times the available power or endurance. With the existing Seabob models already setting a pretty thrilling pace for leisure use, the high performance Magnum will be pitched as a military and special forces tool that will enable operatives to move exceptionally quickly from point to point, underwater and in total silence.
