6-Beam Sensitivity
(6-Beam Sonar View Only)
6-Beam Sensitivity controls how much detail is shown on the display, and is only available
on the X-Press™ Menu when you are in the 6-Beam Sonar View only. 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.
T
o adjust the 6-Beam Sensitivity:
1. Highlight 6-Beam Sensitivity on the Sonar X-Press ™ Menu.
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 History
(3D Sonar, 3D/2D Sonar Combo Views Only)
3D History determines the speed at which the sonar information moves across the
display, and consequently the amount of history shown, and is only available on the
X-Press™ Menu when you are in the 3D Sonar or the 3D/2D Sonar Combo Views. A faster
speed shows less history and is preferred by most anglers; however, the sonar
information moves across the display quickly. A slower speed keeps the information on
the display longer, but the bottom becomes compressed and may be difficult to
interpret. Adjust 3D History to your personal preference.
T
o adjust the 3D Hist
ory:
1. Highlight 3D History on the Sonar X-Press™ Menu.
