Why Choose This Kit?

Dual-Frequency High-Definition Imaging

The C1200D combines two high-definition imaging frequencies within a single sonar platform, providing exceptional flexibility for a wide range of underwater inspection tasks.

The 1.2 MHz channel delivers broad-area coverage with a 136° horizontal field of view, enabling efficient navigation, obstacle avoidance, and large-scale surveys. The 1.8 MHz channel offers significantly higher spatial resolution for close-range inspection, allowing operators to distinguish extremely fine structural features and millimeter-scale targets with remarkable clarity.

This dual-frequency architecture enables a single sonar to perform both wide-area exploration and precision inspection without requiring multiple imaging systems.

Millimeter-Level Detail Recognition

Operating at 1.8 MHz, the C1200D produces exceptionally sharp acoustic imagery capable of resolving fine underwater features that are often beyond the capability of conventional imaging sonars.

The enhanced image definition makes it ideal for inspecting underwater infrastructure, identifying small defects, evaluating structural conditions, and performing detailed engineering surveys where precision is essential.

Wide-Area Coverage with Professional Efficiency

At 1.2 MHz, the sonar provides an ultra-wide 136° horizontal beamwidth, allowing operators to inspect significantly larger underwater areas with fewer scanning passes.

This wide coverage improves operational efficiency, reduces mission time, minimizes blind zones, and enhances target detection during inspection, navigation, and search operations.

Compact Design with Outstanding Adaptability

Despite its advanced imaging capability, the C1200D maintains a compact and lightweight form factor suitable for installation on a wide variety of underwater platforms.

Its versatile mechanical design enables seamless integration into ROVs, AUVs, UUVs, diver-operated systems, and customized underwater robotic platforms, making it suitable for both portable and permanently installed applications.

100% Self-Controlled
