Lower Range

Settings: AUTO, 10 to 1500 ft, 3 to 500 m
[International Models only]; Default = AUTO
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. will be displayed in the lower right corner of the screen to
M
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 fishing in 60 feet of water but are only interested in
the first 30 feet (surface to a depth of 30 feet) you should set the Lower
Depth Range limit to 30. The display will show the 0 to 30 foot range,
which allows you to see a more detailed view than you would see if the
display went all the way to the bottom.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and
Lower Range regardless of the settings entered manually.
Chart Speed determines the speed at which the sonar information moves
across the display, and consequently the amount of detail shown.
A faster speed shows more information and is preferred by most anglers;
however, the sonar information moves across the display quickly. A slower
speed keeps the information on the display longer, but the bottom and fish
details become compressed and may be difficult to interpret.
SI Colors allows you to select which color palette you would like to use for
the Side Imaging® and Down Imaging™ display.
Cancel Navigation discards the current route and exits Navigation Mode.
This menu option will only appear when you are currently navigating a route.
This will not delete a previously-saved route.
