The German Bundeswehr auf Boot? Yes, with a German and a British rebreather!
Unfortunately the guy on the show did not know anything about the Stealth
rebreather of divex....
Also they showed the VERY rarely seen LAR 7 COMBI. This unit is in use with
only a very few countries. The combined closed circuit oxygen rebreather and
semiclosed nitrox rebreather can be switched on the fly. The lever in front
of the diver offers stealth operation in the 0-6 mtr range, then switching
to semiclosed modes offers depth up to 40 mtrs..
