FD-F750M Miniature Forward Looking Sonar

The FD-F750M is a compact, high-performance miniature forward-looking sonar, engineered for space-constrained marine applications. Combining ultra-small form factor, multi-frequency flexibility, and high-precision imaging, it delivers reliable underwater detection and collision avoidance for small vessels, ROVs, and portable survey systems.

Core Advantages

✅ Ultra-Compact & Lightweight Design

•Miniature dimensions (120×60×125mm for 300m model) with only 540g in air / 200g in water, ideal for integration on small platforms.

•Rugged construction: anodized aluminum alloy (300m), optional 316 stainless steel, or titanium (1.5km) for harsh marine environments.

✅ Multi-Frequency Flexibility & High Precision

•Dual/multi-frequency options (375kHz/400kHz/700kHz/750kHz/900kHz/1.2MHz, customizable) with software switchable operation.

•Ultra-narrow beamwidth (0.95°/0.6°at 750kHz/1.2MHz) and 2.5mm range resolution for precise target localization.

•Adjustable vertical beamwidth for single-frequency configurations, adapting to diverse detection needs.

✅ Long Range & Real-Time Performance

• Maximum detection range up to 200m (375kHz model), with 120m/50m at 750kHz/1.2MHz for balanced range and resolution.

• 768 high-density beams and up to 40Hz update rate for smooth, real-time forward imaging.

• 300m or 1.5km working depth options, supporting shallow coastal to deep offshore missions.

✅ User-Friendly & Integrated Safety

•Optional collision avoidance mode, outputting ranges and directions of the top 10 highest-intensity targets for navigation safety.

• Free APP and SDK provided for easy control, data access, and secondary development.

•18~50VDC wide input voltage, ~8W average power consumption, and 100Base-T Ethernet interface for seamless integration.

Key Applications

Perfect for small vessel navigation, ROV/AUV obstacle avoidance, underwater inspection, portable marine survey, and unmanned surface vehicle (USV) operations.
