Range function
The range function allows you to control the
depth range that is displayed on the LCD. There
are three different range modes; Top, Bottom,
and All.
If Top is selected then a lower depth limit value
must also be selected. This mode locks the
display to show only echoes from the surface of
the water down to the lower depth limit you have
selected. This means that the sea bed may not
be shown if the water is deeper than the selected
lower depth limit.
If Bottom is selected then an upper depth limit
must also be entered. This mode locks the
display to show only echoes between the sea
bed and the upper depth limit you have selected.
The top of the water may not be shown if the
water is deeper than the upper depth limit. This
feature is like a ZOOM function, as it allows you
to see the bottom contour and fish echoes above
the bottom in greater detail.
If All is selected then the unit will automatically
adjust the display range to show both the top of
the water and the sea bed no matter what the
depth of the water is.
