Humminbird HELIX 5 SERIES Operation Manual page 92

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.
Sensitivity controls how much detail is shown on the display and will adjust the sensitivity of all
sonar frequencies.
When operating in very clear water or greater depths, increase the sensitivity to see weaker
returns that may be of interest. If the sensitivity is adjusted too high, the display may become too
cluttered.
Decrease the sensitivity to eliminate the clutter from the display that is sometimes present in
murky or muddy water. If Sensitivity is adjusted too low, the display may not show many sonar
returns that could be fish.
NOTE: The Sensitivity setting is a global setting and will adjust the sensitivity of all sonar frequencies.
Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split Sonar,
Circular Flasher, and Big Digits Views. Upper Range is often used with Lower Range.
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 SONAR GPS: 0 to 1490 ft, 0 to 497 m (International Models only); Default = 0
• HELIX DI GPS: 0 to 590 ft, 0 to 237 m (International Models only); Default = 0
• HELIX XD GPS: 0 to 2490 ft, 0 to 757 m (International Models only); Default = 0
