ES3 PT

Product code : 1490505739

The ES3 Multibeam echo sounder is a portable, easy to use system that will collect bathymetry over a 120 swath up to a water depth of up to 60 meters. The small size of the ES3 makes it easy to install on vessels of opportunity and its ease of operation makes it an excellent choice for surveyors who want to make the technical transition from single beam echo sounding to multibeam surveying.
