With an IP68 protection rating, this sensor can replace a camera for obstacle avoidance and meet the requirements of normal underwater navigation speeds. By using this obstacle avoidance sensor, underwater vehicles can achieve true "unmanned driving" without the need for human observation. Even at a depth of 10m, obstacle avoidance can still be easily accomplished.
