C750DH Pro

Designed for Next-Generation Deep-Water Imaging

The C750DH Pro combines the next-generation imaging performance of the C750D Pro with a pressure-rated titanium alloy housing engineered for underwater operations down to 1,000 meters. Designed for professionals working in harsh offshore and deep-water environments, it delivers exceptional acoustic image quality, outstanding target recognition, and long-term reliability under extreme operating conditions.

Built on HANHAI's latest hardware architecture, the C750DH Pro provides ultra-clear real-time sonar imaging with significantly improved signal processing, lower image noise, and enhanced micro-detail detection. Whether operating in complete darkness, turbid water, or high-pressure offshore environments, it delivers dependable situational awareness for mission-critical underwater operations.

The system is designed for seamless integration with professional ROVs, AUVs, UUVs, and custom subsea platforms, supporting offshore inspection, marine engineering, scientific research, subsea infrastructure maintenance, navigation assistance, and search & recovery missions.

The C750DH Pro maintains full compatibility with the Blueprint Subsea Oculus M750D, utilizing the same Teledyne Impulse IE55 connector and identical mounting configurations. Existing systems can therefore be upgraded to next-generation imaging performance and a 1,000-meter operating depth without modifying mechanical interfaces or electrical connections.

Why Choose This Kit?

Next-Generation Hardware Architecture

Powered by HANHAI's latest imaging platform, the C750DH Pro features a completely redesigned hardware architecture with enhanced processing capability and an optimized signal processing pipeline.

The upgraded electronics efficiently process massive volumes of sonar data in real time, reducing acoustic noise while improving target separation, image stability, and fine-detail recognition. The result is exceptionally clean sonar imagery that allows operators to identify underwater structures, pipelines, fish schools, and subsea objects with greater confidence.

Ultra-Wide 136° Field of View

The C750DH Pro features an upgraded 136° horizontal field of view, providing substantially greater coverage during every scan compared with conventional imaging sonars.

The wider viewing angle enables faster area surveys, minimizes blind spots, and significantly improves target acquisition efficiency during navigation, inspection, and search operations. Operators can inspect larger underwater areas with fewer passes, reducing mission time while increasing operational efficiency.

Titanium Housing for Offshore Reliability

Unlike the standard C750D Pro, the C750DH Pro utilizes a precision-machined titanium alloy pressure housing rated for continuous operation at depths of 1,000 meters.

Titanium offers exceptional resistance to corrosion, pressure fatigue, and long-term seawater exposure while maintaining excellent structural strength and dimensional stability. This makes the C750DH Pro particularly well suited for offshore engineering, scientific research, underwater infrastructure inspection, and other demanding marine applications where durability is essential.

100% Self-Controlled

Developed with complete independent intellectual property rights, the C750DH Pro provides customers with full control over integration and future development.

A comprehensive SDK supports OEM integration, autonomous underwater vehicle development, custom mission software, AI-assisted perception, and industry-specific application development.

Seamless Platform Integration

Maintaining the same connector interface and mounting dimensions as the Oculus M750D, the C750DH Pro integrates easily into existing underwater vehicles without requiring structural modifications.

Its compact design, standardized interfaces, and low power consumption make it suitable for inspection-class ROVs, work-class ROVs, AUVs, UUVs, portable survey systems, and customized underwater robotic platforms operating in deep-water environments.
