Upper Range
(Advanced: Sonar, Split Sonar, Circular Flasher, and Big Digits Views only)
Settings: 0 to 990 ft or 0 to 327 m [International Models only]; Default = 0
Upper Range sets the shallowestdepth range that will be displayed onthe Sonar, Split Sonar, Circular Flasher, and Big Digits 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 surfac e or the bottom (assuming the bottom is deeper than 50 feet). Greater detail will be shown for the area between 20 and 50 feet.
NOTE: A minimum distance of 10 feet will be maint ained between the Upper and Lower Range regardless of the manual settings entered.
Lower Range
Settings: AUTO, 10 to 1000 ft, 3 to 330 m [International
Models only]; Default = AUTO
Lower Range sets the deepest depth range that will be displayed by the unit.
Auto: The L ower Range will be adjus ted by the unit to f ollow 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 Ma nual mode. Adjus t the Upper an d Lo wer Ra nge to gether 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 interest ed in the first 30 feet (surface to a depth of 30 fe et), 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 dis play 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 manual settings entered.
