MultiBeam Sonar Option
The Imagenex Delta-T profiling sonar option is fully integrated into
the VectorMAP (mission planner) for setting up sonar tracks.
This option can be combined with a DVL for improved positional accuracy. The multibeam
sonar is provided as a 12" wet section to the EP30 vehicle and the ideal
solution for a variety of survey requirements.
