• Vivid 16-color color, echo strength dependent display for improved recognition of sea- bed, fish school concentration, distribution and volume.

• Memory card for storage and replay of sonar picture (whole screen or echo inside esti- mate mark), net shooting data, ship's track, tidal current data, etc.

• Function keys for customized operation.

• Menu-driven operation with help screen.

• Wide variety of display modes: normal sonar picture, echo sounder combination, histrical display combination, port/starboard display, horizontal slice, target slice, and unique ver- tical scanning.
