The BL200 is a Survey Grade Single beam Echosounder and is the best choice for shallow water bathymetric surveys up to 100 meters deep. This unit has an embedded transceiver with digital signal processing. Its “smart”. It adjusts power and gain as needed, it knows how deep it is and when it has bottom track. This is the most portable Survey Grade Echosounder made today. The Bathylogger delivers the same accuracy as the best Survey transducers in the world 1cm +/- every 10 meters of depth. The simplicity is in the design, less is more. It can tackle saltwater or freshwater from lakes and rivers to Ports and Harbours.
