Scanning Sonar Testing

It calculates the sound velocity using the measured temperature and given salinity.
Thanks for the hint @etienne , they probably don’t do it just for fun so I’ll experiment a bit with the velocity setting. Unfortunately I don’t have a velocity probe but I’ll use the distance from the RTK-GPS to adjust it (this one works pretty well :smiley: )

Has anyone tried the JW Fishers SCAN-650?
