Description
The Chasing Distance Lock Sonar is an advanced obstacle avoidance and positioning accessory designed for the CHASING M2 PRO MAX ROV. Engineered for professional underwater operations, this sonar system enables fixed-distance navigation and real-time anti-collision in four key directions: front, down, left, and right. It ensures greater safety, stability, and control when operating in tight or obstacle-rich underwater environments.
Equipped with precision sonar sensors, the system continuously monitors the ROV’s surroundings. It intelligently adjusts movement and maintains a preset safe distance from underwater objects such as walls, seabeds, ship hulls, or marine structures. This is especially critical in inspection, survey, and salvage tasks, where close-quarters maneuvering is required.
The Distance Lock Sonar includes a Quick Mounting Package, making installation fast and tool-free. This setup enables rapid deployment in the field without slowing down operations. Once mounted, the system integrates seamlessly with the M2 PRO MAX’s onboard software, displaying sonar data in real time and assisting with accurate path planning.
The sonar provides clear benefits for operators working in complex marine environments — minimizing collision risk, maintaining depth, and enhancing overall mission precision. It also supports the stability of robotic arm operations and other mounted accessories by holding a fixed position during use.
Whether you’re conducting infrastructure inspections, aquaculture monitoring, or underwater research, the Chasing Distance Lock Sonar adds an essential layer of intelligence and protection to your ROV workflow.
