SCUBAJET is a new underwater scooter for propelling your person while diving. You can also attach the water jet to small watercraft, such as a stand up paddleboard, canoe, or kayak. No word yet on whether or now it's compatible with the Inflat-a-Bull, but the Austrian company developing the SCUBAJET will begin shipping them in August, so you could be the first to find out.
We've seen these types of jet propulsion systems for subsurface good times before in the Underwater Jetpack and the BladeFish personal water jet, but the Jetpack is designed exclusively for swimming and diving (and costs twice as much) and the BladeFish peaks out at speeds of 3MPH.
While not without limitations, and not cheap itself, the SCUBAJET offers the same portability and ease of use as its peers, with more versatility and power. It weighs just 6.6 pounds on land, so basically nothing in water, and has optional remote control for when it's mounted to a board or boat. And it can scoot you along at up to 10MPH, with 44 pounds of thrust.
SCUBAJETs come with either 200W or 400W batteries, with run times per charge that vary significantly base on your activity and speed. For boat / board safety they have an auto-shutoff system that stops the jet immediately if you fall into the water.
