  • 3D Scanning Sonar DASS710 and SAMM

The DASS710 is an ultra-compact 3D scanning sonar that combines powerful scanning capabilities in a compact form, providing versatility for efficient underwater exploration. It is equipped with high-resolution pencil beams from a broadband composite transducer, ensuring detailed and accurate imaging of the underwater environment. Users can choose between a full 360° horizontal scan or a customized sector scan (200° vertical) for flexibility in adapting to specific survey requirements.

The sonar generates 3D point clouds with exceptional precision, offering a comprehensive representation of underwater structures and dynamics. It achieves meticulous altitude range resolution, capable of detecting changes as small as 1mm, ensuring precision in monitoring underwater features. The scanning precision is adjustable, with an angular resolution as fine as 0.1 degrees, allowing for customized survey configurations.

Weighing a mere 2.2kg in air and with dimensions of D110 x H150mm, the DASS710 is exceptionally lightweight and compact, facilitating easy deployment and handling. It offers two deployment modes – standalone deployment for independent surveys or daisy chain mode with an RS-485 network for enhanced capabilities and extended coverage.

The DASS710 seamlessly integrates with various commercial and open-source software packages, including EIVA NaviSuite and Cloud Compare, ensuring compatibility with industry-standard tools for data analysis.
