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.
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 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.
The available Lower Range settings are determined by your Humminbird model as follows:
• HELIX SONAR GPS: Auto to 1500 ft, Auto to 500 m (International Models only);
Default = Auto
• HELIX DI GPS: Auto to 600 ft, Auto to 240 m (International Models only); Default = Auto
• HELIX XD GPS: Auto to 2500 ft, Auto to 760 m (International Models only); Default = Auto
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. Regardless of the Chart Speed setting, the RTS Window will update at the maximum
rate possible for the depth conditions.
