Color Bar
Colored scale located on the left side of the screen that shows the colors
used in the Echogram to represent the echoes strength. The color on the
top of the bar represents the maximum sonar strength, while the color on
the bottom of the bar represents the minimum sonar strength. It shows red
(the strongest), orange (strong), yellow (medium), green (weaker), and
blue (the weakest).
Digital Depth
Readout of the current bottom depth.
Water Temperature
Readout of the current water temperature returned by the TEMP 1 sensor
included into specific transducers.
Alarm Bar
Bars showing the shallow water and deep water alarm values. The alarm is
triggered when depth is outside the range.
Depth ruler
Vertical graduated bar. It is a scale which reflects the depth of the area
being displayed.
Variable Depth Marker (VDM)
Horizontal line on to the Echogram window with a depth label. The up/
down cursor buttons can move it up and down. The label displays the
depth of the cursor position. It can be moved to any location pinpointing
the depth of a target.

zoomed window (on the left part of the screen). It is turned on selecting
Zoom Full display page.
A-Scope
A real time representation of fish and bottom features passing through the
beam of the transducer. It is drawn as horizontal lines whose length and
hue is proportional to the sonar strength returned. When the default palette
is selected, the strongest sonar returns will be shown as the color
displayed of the top of Color Bar while the weakest as the bottom color.
This feature is useful for close observation of small fish and fish near the
bottom.
Operating Frequency
Readout of the selected operating frequency.
