SEA CHARIOT L380
Highly Maneuverable Underwater Vehicle (Max Depth: 20m; Deeper Versions Available)
The SEA CHARIOT L380 is an underwater vehicle for recreational, commercial, and military tasks to a maximum depth of 20 meters, with deeper versions available on request. Applications include wreck exploration, photography, archaeology, fish farming, coral restoration, and marine biology. It carries three people (two divers and a diver-pilot) for about five hours, or two people with large-format photography equipment. Four 500-watt BLDC thrusters are powered by a 36V 200Ah lithium battery bank in a deep-water waterproof housing. An Arduino CPU assists the diver-pilot. The stable platform is suited to motion-picture and regular video photography. The craft includes an onboard 60-liter air bank, air-content and depth gauges, and a surface flotation system.
