Sensitivity

Sensitivity controls how much detail is shown on the display and will adjust the sensitivity of all sonar frequencies. Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the sensitivity eliminates 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, as compared to specific sensitivity adjustments (such as 83 kHz Sensitivity, 455 kHz Balance or Wideside Sensitivity) that allow you to adjust the level of sensitivity for one specific beam at a time.

Sensitivity at Low

Sensitivity at Medium

Sensitivity at High

To adjust the Sensitivity:

1.Highlight Sensitivity on the Sonar X-PressTMmenu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Sensitivity setting. (Low = 1, High = 20, Default = 10)

Upper Range

(Advanced: Sonar, Split Sonar, Big Digits and Circular Flasher

views only)

Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split Sonar, Big Digits and Circular Flasher Views. The Upper Range menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be accessed from the Sonar, Split Sonar, Big Digits and Circular Flasher 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.

To adjust the Upper Range:

1.Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar X-PressTMmenu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Upper Range setting. (0 to 1490 feet or 0 to 497 meters [International Models only], Default = 0)
