Diving scooter over a wreck. This is a Bellaqua breathing observation bubble (BOB). It has a clear acrylic dome that covers the diver's head as the diver sits on a motorbike-style seat. The air inside the dome is supplied by a standard scuba tank. The scooter moves at up to 5 kilometres an hour with an electrically-powered propeller. A buoyancy-control device is used to ascend and descend to depths of up to 12 metres. A dive computer monitors the dive, which lasts for about 40 minutes.
