The BL200 is a Survey Grade 200 kHz Single beam Echo sounder (sonar) 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 Echo sounder 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 Harbors. Perfect for Hydrographic Surveys, Bridge Scouring, Dredging Surveys, Mining Tailings ponds and more. Compatible with ALL manufacturers: Trimble, Leica, Topcon, Socchia , Carlson, Hemisphere, Hypack, Hydromagic, Quinsy and more. The BL200 Meets USACE Specs and is made in the USA.
Included is our very own Bathylogger Control Software for a PC. With this you can adjust the sound velocity and output ping rate 1 – 10 hz, It also has a built in terminal program to view output data.
Echo Sounding Sonar uses the time interval between a series of soundings and echos for several purposes like range finding (survey) , fish finding or imaging. The bathy logger is a single beam , single frequency 200 kHz echo sounder made for conducting survey grade bathymetric ( Hydrographic ) surveys. Over 90% of bathymetric surveys in the world are still done with single beam echo sounders. Survey Echo sounders have a narrower beam (cone) and can not see fish in the water column. We just want to track the bottom and interpret the returns for accuracy unlike a fish finder.
