you know BOB – the Breathing Observation Bubble? and then there is HydroBOB, an underwater scooter that allows you to roam the underwater without diving training or even if do not know how to swim. HydroBOB is the combination of the BOB with a scooter that scoots around under the water. all you have to do is pops your head into the bubble and ride like a scooter. your head don’t get wet, so those with glasses still can wear them while scooting around underwater. very nice. this is something i really want to try. wonder how well it works in open sea, with the underwater current and all that. but i got one question: what happens if you bumped into a shark well scooting underwater? hmmmm.
check some clips on youtube about the Underwater Scooter.
