Fish finders with fish symbols indication

Indication of symbols in the form of fish

— displaying fish marks on the sonar screen in the form of characteristic “fish” icons. This display option is typical for devices designed for amateur anglers: symbols in the form of fish are clearer and easier for an inexperienced user to perceive than standard arcs (the latter are more informative, but a certain skill is needed to work effectively with this information). In addition, this function often also involves automatic recognition of the size of the fish and its separation from other types of signal.
