6-Beam Sensitivity

(6-Beam Sonar View only)

6-Beam Sensitivity controls how much detail is shown on the display, and
is only available when you are in the 6-Beam Sonar View. Increasing the
sensitivity shows more sonar returns from small baitfish and suspended
debris in the water; the display may become too cluttered, however. 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.

To adjust the 6-Beam Sensitivity:

1. Highlight 6-Beam Sensitivity on the X-Press™ menu while in the

6-Beam Sonar View.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or

decrease the 6-Beam Sensitivity setting. (Low = 1, High = 20,
Default = 10)

3D Bottom Zoom

3D Bottom Zoom provides a magnified

image of the bottom, and is only available on the 3D Sonar X-Press™ Menu
in the 3D Sonar View and the 3D/2D Sonar Combo View. Use 3D Bottom
Zoom to increase the detail of the bottom on the display.

To adjust the 3D Bottom Zoom:

1. Highlight 3D Bottom Zoom on the 3D Sonar X-Press™ Menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 3D

Bottom Zoom setting. (Off, 1.5x, 2x, 2.5x, 3x, Default = Off)

3D Lower Range

3D Lower Range sets the deepest depth

range that will be displayed, and is only available on the 3D Sonar
X-Press™ Menu when you are in the 3D Sonar, 3D/2D Sonar Combo, or the
6-Beam Sonar View. Automatic is the default setting. When in automatic
mode, the lower range will be adjusted by the unit to follow the bottom.
Selecting a specific setting locks the depth range into Manual mode.

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, allowing you to see a more detailed view than
you would see if the display went all the way to the bottom.
