Production Prototypes in early 2011

In March the production prototypes of the Razor 2 system were used already to connect Sistema Naranjal to Sistema Ox Bel Ha. The Razor 2 system was tested in real world conditions and performed perfect.
That made Ox Bel Ha once again the world’s Longest Underwater Cave System at 710,000+ feet/ 216,450 meters.
At the same time HP went to cold water diving in Europe to test the system for cold water.
