Top Images: Heavy sub-aquatic vegetation. For example, heavy bottom vegetation may be identified on the echogram and differentiated from the true bottom, a process that may be impossible with a basic echo sounder. When it comes to reviewing data quality in real time and after the survey is completed, the echogram record presents a crucial advantage over basic echo sounders that output only the digital depth sounding value. The intensity of the echo return from the entire water column and sub-bottom is recorded, not just the single sounding depth value for each ping. In addition to the sounding depth output, the complete sonar echo return from each ping is digitized into 3200 separate and discrete values from just below the surface to the sub-bottom level. The CEE ECHO™ and CEESCOPE™ echo sounders can log soundings at up to 20 Hz, providing exceptional bottom detail along the survey track.
