What do fish look like in the forward scan? Are there fish symbols?
Because forward scanning sonar is true sonar, we do not create artificial fish symbols. Our sonar systems are used for research, search and rescue as well as fishing and navigational safety. Therefore, we try to produce the most accurate returns possible to provide the highest quality of sonar information to the wide variety of applications of our products. Fish appear differently on forward scanning sonar than they do on traditional down-looking fish-finders. When any sonar ‘pings’ a fish, the sonar signal reflects off of the air bladder of the fish. This is how professional tournament fishermen are able to tell different species of fish on their fish-finders. They recognize the pattern of the air bladder in particular fish. A down-looking sonar strikes the fish along the spine and the air bladder can then produce a ‘fish arch’. Fish-finders that display fish symbols look for this arch and any other suspended returns and display them as fish, whether they actually are or not.
