Whether you’re diving, snorkelling, canoeing, or on a stand up paddleboard, the Scubajet can lessen the effort needed to move on water, essentially bringing it down to zero. It parallels e-bike conversion kits that motorize your bike: using one of various adapters tailored to various watercraft, Scubajet attaches to where the fin would have on paddleboards or hooks up to the back of a dinghy like an outboard motor. Once affixed it provides speeds of between 5 and 10 miles per hour for as long as 4 hours with the optional larger internal battery or triple that with an optional and upcoming external battery pack. It’s also safe since there are no exposed propellors, light in weight at just six and a half pounds, and comes with a water resistant remote control to adjust speeds.
