Russian engineers designed a new portable training device for divers, which can also be useful for rescue rangers, who do not have such training facilities yet.
      
      New facility allows full training of a diver in an ordinary room. It is an insulated 2x3 meter vessel, filled with water. Wall of the device are transparent, which allows a coach to keep an eye on his trainees. Everything a diver does is recorded by two video cameras and can later be discussed.
      
      The vessel, holding 15 tons of water, has a split body, consisting of 7 components. Thus, the vessel can be conveniently delivered to desired place by air or railway.
