Depth Lines divide the display into four equal sections which are separated by three horizontal depth lines. The depth of each line is displayed along the depth scale. You can turn Depth Lines On or Off.

Noise Filter adjusts the sonar Noise Filter to limit interference on the display from sources such as your boat engine, turbulence, or other sonar devices.
The Off setting removes all filtering. Low, Medium, and High1, High2, High3 settings add progressive filtering of the sonar returns. High1, High2, and High3 are useful when there is excessive trolling motor noise, but in some deep water situations, the High settings may actually hinder your unit’s ability to find the bottom.
