6.3 What can the fishfinder show me?

When you first view the fishfinder application, an image representing the echoes seen
by the DSM is displayed. As time passes this image scrolls from right to left and
becomes a record of the echoes seen. The images at the right hand side of the display
are therefore the most recent.
The fishfinder window will display:
• The bottom together with any bottom structure such as reefs and shipwrecks etc.
• Target images indicating fish.
• A status bar noting the frequency and gain settings.
• The bottom depth.
You can customize the fishfinder to:
• Hide the depth of the targets - see
• Show the depth lines - see
• Change the color palette and the depth displayed - see
• Pause or change the scroll speed - see
• Enable a fish, shallow or deep water alarm - see
• Adjust the DSM and Transducer to suit local conditions - see
