C1200DH

Designed for Flagship Deep-Water High-Definition Imaging

The C1200DH is HANHAI's flagship deep-water dual-frequency high-definition imaging sonar, combining industry-leading image quality with a 1,000-meter pressure-rated titanium alloy housing for demanding offshore and subsea applications.

Operating at 1.2 MHz and 1.8 MHz, the C1200DH delivers exceptional acoustic imaging across both wide-area surveys and ultra-high-resolution close-range inspections. The 1.2 MHz frequency provides a wide 136° horizontal field of view for efficient large-area coverage, while the 1.8 MHz frequency produces ultra-high-definition sonar imagery capable of resolving millimeter-level details, making it ideal for precision underwater inspection.

Designed for professional deployment on ROVs, AUVs, UUVs, diver systems, and customized subsea platforms, the C1200DH delivers dependable real-time imaging in complete darkness, highly turbid water, and high-pressure offshore environments where optical cameras cannot operate effectively.

The C1200DH combines a compact mechanical design with a robust titanium pressure housing, allowing straightforward integration into professional underwater vehicles while providing the durability required for continuous operation at depths of up to 1,000 meters.

Why Choose This Kit?

Dual-Frequency High-Definition Imaging

The C1200DH integrates two high-definition imaging frequencies into one compact sonar platform, enabling operators to switch seamlessly between wide-area surveys and ultra-precise close-range inspections.

The 1.2 MHz channel provides a 136° ultra-wide field of view, allowing efficient coverage of large underwater areas, while the 1.8 MHz channel delivers exceptional image resolution capable of revealing millimeter-scale structural details for critical inspection tasks.

This dual-frequency architecture provides maximum operational flexibility while eliminating the need for multiple sonar systems.

Millimeter-Level Precision Inspection

Designed for professional inspection applications, the 1.8 MHz imaging channel produces exceptionally sharp acoustic images with outstanding target definition.

Whether inspecting underwater infrastructure, offshore equipment, pipelines, marine structures, or scientific research targets, the C1200DH enables operators to distinguish fine structural features that are difficult to identify using conventional imaging sonars.

Titanium Housing for Deep-Water Reliability

Unlike standard aluminum-housed imaging sonars, the C1200DH features a precision-machined titanium alloy pressure housing engineered for continuous operation at depths of up to 1,000 meters.

Titanium offers outstanding corrosion resistance, superior mechanical strength, and exceptional long-term durability in harsh marine environments. The robust housing ensures stable imaging performance during extended offshore missions while minimizing maintenance requirements and maximizing operational reliability.

100% Self-Controlled

The C1200DH is developed with complete independent intellectual property rights, representing HANHAI's highest level of domestic underwater imaging technology.

From acoustic transducer design and electronic hardware to signal processing algorithms and application software, every core technology has been independently developed to ensure long-term product support, continuous innovation, and complete system flexibility.

A comprehensive SDK enables OEM integration, customized software development, autonomous underwater vehicle applications, AI-assisted perception, and advanced mission-specific functionality.

Professional Platform Integration

The compact dimensions and standardized interfaces enable the C1200DH to integrate seamlessly with inspection-class ROVs, work-class ROVs, AUVs, UUVs, diver-operated systems, and customized subsea robotic platforms.

Its high-performance imaging capability, rugged titanium construction, and low power consumption make it equally suitable for permanent installation, portable deployment, and OEM integration projects operating in demanding offshore environments.
