Welcome to the Raymarine Forum Randy,

Raymarine fishfinding products do not support displaying fish icons on the fishfinder plot. Prior to the introduction of the DSM250, Raymarine's first product featuring Digital Sounder Technology, fish arches were common. The limitation of such arches is the less information is conveyed concerning the relative size and number of fish are present. Digital sounder technology permits fish (more precisely the swim bladders of these fish) to be plotted as individual targets. The larger fish typically have larger swim bladders and will be plotted as larger targets relative to smaller fish being sensed by the system.
