The FF-M is a compact ranging sonar module specifically designed for underwater vehicles (ROV / AUV / Glider), ideal for collision avoidance, distance measurement, and environmental sensing applications. Featuring a dual-frequency acoustic design and high directivity, it enables accurate detection of underwater obstacles, supporting both short-range avoidance and mid- to long-range ranging requirements.

Engineered with a reinforced housing and high-insulation materials, the FF-M offers excellent pressure resistance and stable performance in deep and high-pressure environments. Its compact form factor and standardized mounting interface allow for seamless integration into a wide range of underwater platforms, significantly improving system development efficiency. Combining reliability, precision, and cost-effectiveness, the FF-M serves as a critical sensing component for underwater vehicle development, with applications in autonomous navigation, environmental perception, and mission safety assurance.
