School of fish

Picture doesn't look like much until you consider the distance they are away from the sonar transducer-vertical pink line thru image is a 25 Meter marker so they are approx 82 feet away and taken at 900 khz. A school of fish that are big by any measure, I am guessing bass perhaps salmon.

Small white lines are the fish and the black lines to the right are the shadows from the fish.

Because the white images do not connect (touch) the black images I know they are objects are suspended off the lake bottom...fish in this case.
