Grab a scooter and dive...this is fun to ride, and it's easy to control. Roughly 4 mps top speed and 90' battery autonomy. This is a safe and confortable way to reach favourite spots faster. I've experienced it a couple of times and just became a fan. It requires some adjustments to the gear, namely the buoyancy compensator.
It's certainly an experience any diver should try.
