I wish I had an X-Scooter CUDA! Scooters are fun freediving and allow fairly deep dives easily, but much more fun on scuba.
Edit: Seabob, "Speed under water up to: 16 km/h (9.9 mph)" Anything over about 3.5 mph will rip the mask off your face. Not sure how they are usable?
My cheapo scooter, that now has plenty of custom mods to improve performance and usability.
