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.
To 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)
