1.2 What the Sounder Displays

When you first view the Fishfinder application on the A65, an image representing
the echoes received by the DSM is displayed. As time passes this image scrolls
from right to left and becomes a record of the data collected. 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
• Target images indicating fish
• The bottom depth
You can customize the sounder to:
• Display or hide the depth of the targets
• Display or hide the depth lines
• Change the color palette
• Change the zoom level
• Pause the scrolling image
• Display White Line or Bottom Fill features
• Enable a fish, shallow or deep water alarm
