Unforgettable diving can be done not only with scuba diving, but also in a personal triple boat Mk.1C from the Dutch manufacturer Ortega. In its arsenal, the submarine has everything the same as an ordinary submarine, only in miniature and without military equipment. There is an onboard breathing apparatus, a HUD navigation system, a magnetometer, a locator, infrared cameras, a cargo compartment of 250 liters, two powerful silent electric motors and a battery, which will be fully charged for 148 km. Mk.1C is able to move both on the surface of the water with a maximum speed of 16 km / h, and under the water column. In the second case, movement can reach 20.4 km / h. All avionics support diving to a depth of 95 meters. The cost of the underwater vehicle is not reported.
