Lower Range
Settings: Various, see below.
Lower Range sets the deepest depth range that will be displayed by the unit.
Auto: The Lower Range will be adjusted by the unit to follow the bottom
automatically. Auto is the default setting.
Manual: You can adjust the Lower Range to lock the unit on a particular depth.
“M” will be displayed in the lower right corner of the screen to indicate the unit
is in Manual mode. Adjust the Upper and Lower Range together to view a
specific depth range, especially when looking for fish or bottom structure.
For example, if you are only interested in the area between 20 and 50 feet
deep,youshould settheUpperDepth Range to20andthe LowerDepthRange
to 50. The SonarView willthen show the30 foot area between20 and 50 and
will not show the surface or the bottom (assuming the bottom is deeper than
50 feet). Greater detail will be shown for the area between 20 and 50 feet.
