The MRS900 series, comprising the MRS900, MRS900L, and MRS900S, stands as a remarkable trio of mini scanning sonar systems, each tailored to distinct underwater environments with pressure ratings of 2000m, 1000m, and 300m, respectively. Renowned for their compact design and advanced features, these sonar systems redefine underwater imaging capabilities, offering unparalleled performance in the marine exploration domain.
As one of the most compact mechanical scanning sonar systems available, the MRS900 series boasts a minimal weight, starting from 380g (140g in water). This lightweight profile, coupled with its compact design, facilitates easy deployment, making it an ideal choice for various underwater applications.
The image quality of the MRS900 series is elevated by the incorporation of CHIRP technology, surpassing its competitors in clarity and resolution. This technological innovation allows for real-time underwater imaging using acoustics, providing operators with a detailed and accurate representation of the underwater terrain.
A key feature distinguishing the MRS900 series is its non-contact rotational scanning mechanism. This mechanism ensures low noise, frictionless scanning, enabling the sonar systems to operate seamlessly for extended periods without breakdowns. This reliability is crucial for sustained underwater exploration and navigation, particularly for Remote Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs).
Designed optimally for the navigation of underwater vehicles, the MRS900 series offers high-resolution images through its piezo-composite broadband transducer. The digital CHIRP technology further enhances the imaging capabilities, providing a clear and detailed view of the underwater surroundings.
