Humminbird HELIX 5 SONAR Operation Manual page 52

Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split Sonar,
Circular Flasher, Big Digits, and Down Imaging/Sonar Combo Views. Upper Range is often used
with Lower Range.
For example, if you are only interested in the area between 20 and 50 feet deep, you should set
the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show
the 30 foot area between 20 and 50, and will not show the surface or the bottom (assuming the
bottom is deeper than 50 feet), and will show greater detail for that area between 20 and 50 feet.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range
regardless of the manual settings entered.
The available Upper Range settings are determined by your Humminbird model as follows:
• HELIX 5 SONAR: 0 to 1490 feet or 0 to 454 meters; Default = 0
• HELIX 5 DI: 0 to 590 feet or 0 to 180 meters; Default = 0
• HELIX 7 SONAR: 0 to 1490 feet or 0 to 454 meters (International Models only); Default = 0
• HELIX 7 DI: 0 to 590 feet or 0 to 180 meters (International Models only); Default = 0
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.
