The Sublue is a watercraft that cannot be registered in Switzerland, making it prohibited in Swiss lakes and rivers. However, the Sublue can be used in swimming pools in Switzerland or, of course, in oceans worldwide. The Sublue White Shark Mix is the first underwater scooter that can be transported as carry-on luggage on airplanes. Ultra-quiet (50 dB) yet powerful, it reaches a maximum speed of 5.4 km/h with its dual propeller drive. Weighing only 2.9 kg, including the battery, it is also easy to transport. It can be used at a diving depth of up to 40 meters.
