Longer test hours for superior stability
In the test at Duck Lake, the BD400D accumulated more than 3,000 test hours. Compared to other products on the market, the BD400D can work continuously and stably for a longer period of time without the need for frequent calibration or maintenance. This advantage not only means higher work efficiency, but also reflects the maturity and stability of product design. The long-term uninterrupted test verifies the reliability and durability of the BD400D in complex underwater environments, which is especially important in underwater emergency rescue missions, providing commanders with more reliable data guarantee and decision-making basis, and effectively improving rescue efficiency and success rate.

Collect massive amounts of data and keep the details under control
In terms of data collection, BD400D has ultra-high resolution and wide coverage angle, detection distance (slant distance) of 0.5m~200m, scanning width, typical 150° (maximum 180°), which makes the scanning efficiency higher and more abundant data in the same test area. This data not only contains precise information about the underwater topography, but also covers more details of the underwater target, such as location, shape, size, etc. The increase in the amount of data collected provides a more solid foundation for subsequent data analysis, processing and application, which helps emergency rescuers to have a more comprehensive understanding of the underwater environment and provides more accurate guidance for underwater operations.

The image algorithm is better and the imaging effect is clearer
In terms of image algorithms, BD400D has developed innovative algorithms based on massive testing and data collection, which can generate high-definition 3D images and videos in real time, including 3D point cloud maps, waterfall intensity maps and bathymetry maps. These images are not only rich in color and layered, but also more precise in detail, clearly showing the undulations of the underwater terrain and the morphological characteristics of the target. The BD400D's images are more intuitive and easy to understand, providing a more convenient means of observation and analysis for emergency rescue operations.

BD400D has the characteristics of small size, light weight and high integration, which is especially suitable for installation in small space platforms such as rescue boats, rubber boats, submersibles, underwater robots, etc., and provides a safer and more reliable technical support for emergency, firefighting and rescue teams. Continuously maintaining tests in different working environments, continuously updating iterative data and algorithms, 3D search and rescue sonar BD400D will become an important means and core equipment in the field of emergency rescue.
