KikFin Shark Underwater Jet Pack
Swim like the open water's apex predator in more ways than one with the KikFin Shark Underwater Jet Pack. It has two pectoral-shaped motorized fins and an IP68-sealed, rechargeable, underwater-swappable battery that doubles as a dorsal back fin for maneuverability. Speeds up to 8 mph are possible, controlled via a wireless glove remote, and changing direction is as easy as moving your head in the direction you want to go. Thanks to the passive cooling the battery receives as it moves through the water, it provides up to 90 minutes of run time per charge. The KikFin Shark is available for pre-order now.
