They do show fish or shoals of fish however the sonar works on reflecting a signal from them and it can be confused by seaweed or in fresh water thermoclines.

http://www8.garmin.com/manuals/FishF...nersManual.pdf The sim bit is on page 33.
We seem to get fish indicated when slowing down caused by bubbles from the prop.
