C-Researcher 3 is a range of versatile submarines for scientists, researchers, makers of documentary films and amateurs who want to explore the underwater world. The crystal-clear, fully acrylic pressure hull with a titanium hatch is positioned at the front of the 3.75 metre long submarine, guaranteeing an unimpeded view. The acrylic sphere provides an ergonomic climate-controlled environment for a pilot and two passengers for up to 18 hours underwater. The boat’s hydrodynamic design allows it to dive to a depth of 1,140 metres.
