When it comes to underwater scooters, there are smaller, less powerful single-motor models, or larger, faster dual-motor units. The new WhiteShark Tini, however, can be used in either configuration.
Designed by Chinese company Sublue (which previously brought us the WhiteShark Mix Pro and Seabow underwater scooters) the Tini has a single motor/thruster that reportedly pulls users along at either of two preset speeds: 1.1 or 1.4 meters (3.6 or 4.6 ft) per second.
It can descend to a maximum depth of 30 m (98 ft), with one 2-hour charge of its lithium battery reportedly good for about 45 minutes of use.
Although it’s neutrally buoyant by default, a “floater” module can be attached to the top, making it positively buoyant. This means that if you let go of it, it will float to the surface. On land, it tips the scales at a claimed 3 kg (6.6 lb).
