Chapter 4: Fishfinder Setup
4.1 DSM Setup
This section details parameters listed in the Fishfinder Setup menu.
Depth Digit Size
This setting controls the size of the digital depth readout at the lower left of the
Fishfinder screen. Choose from the following:
• LARGE (default)
• SMALL

Horizontal dashed lines drawn at regular intervals to indicate the depth from the

Palette
The DSM25 offers you six different display color combinations. You can select the
color set for a bold or soft color palette. The brightness of the screen can be
adjusted over a wide range, suitable for viewing in daylight (high brightness level)
or at night (low brightness level).
Select the optimal color scheme for your lighting conditions:
• CLASSIC/BLUE (default)
• CLASSIC/WHITE
• CLASSIC/BLACK
• SUNBURST
• GRAYSCALE
• INV. GRAY
• COPPER
• NIGHT VISION
You will probably find that you need to change the background color in different
light conditions. For example, CLASSIC/WHITE is probably easiest to see in bright
sunlight, but CLASSIC/BLACK or NIGHT VISION may be preferable at night.
