It's equipped with 450 Watts of LED lighting, two sets of parallel lasers which provide approximate scale to objects seen in the video, a forward-looking, obstacle-avoidance scanning sonar, real-time gigabit data telemetry, and 150 Watts of additional payload power available for mission specific temporary instrumentation. It is capable of operating in water depths up 700 meters. The system requires hydraulic power for a small deck winch, 120 volt AC power, and dry lab space on the vessel for monitors and equipment."
