Activities and equipment

Activity	Equipment
10CCT03	Multibeam Bathymetry System Ultra high resolution portable multibeam echosounder. The SeaBat T50-P is fully frequency agile from 190 to 420 kHz allowing for improved swath performance and reduced survey time under difficult conditions. The SeaBat T50-P is designed for fast mobilization on smaller vessels. The Portable Sonar Processor and sonar head form a compact system, securing minimal interfacing and low space requirements. SPCMSC system consists of two T50-P units that are linked together to form a dual head system.
