  • 3D Scanning Sonar DASS710 and SAMM

Point cloud enabled high resolution 3D scanning imaging sonar for underwater structure monitoring. The 3D sonar Echologger DASS710 is the ideal tool for scour monitoring.

The dual axis scanning sonar, DASS710 is a realtime 3D sonar and can be deployed with a stand alone or daisy chain mode using an RS-485 network. The 3D point clouds produced by DASS710 are in a very high resolution generated from a high frequency sharp pencil beam composite transducer, which is very useful for studying the dynamics of sediment scour and aggregation as well as for monitoring underwater structures. The DASS710 3D sonar provides an X, Y, Z cloud points output which is compatible with various commercial and open source software packages including EIVA NaviSuite and Cloud Compare. It can also output intensity and backstcatter data along with point clouds.
