Note: The spot sounding range setting allows you to control the color (or shade)
associated to user assigned depths. Any contour line area that contains a
depth that is LOWER than the first number will be shown in dark blue
(dark tone). Any contour line area that contains a depth BETWEEN the
first and second number will be shown as light blue (medium tone). Any
contour line area that contain a depth that is HIGHER than the second
number will be white (light tone). For example, if the spot sounding range
setting is set to 0010-00010 ft, all contour areas that contain any depth
less than 10 ft deep would be shaded dark blue (dark tone), all depth
contour areas that contain a depth between 10 and 50 feet will be shaded
light blue (medium tone), and all contour areas over 50 feet deep will be
white (light tone).
