Depth Lines
(Advanced)
Settings: Off, On; Default = On
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
(Advanced)
Settings: Off, Low, Medium, High 1, High 2, High 3; Default = Low
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 High 1, High 2, High 3 settings add
progressive filtering of the sonar returns. High 1, High 2, and High 3 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.
Max Depth
(Advanced)
Settings: Various, see below.
Max Depth
controls the maximum depth of operation. When Max Depth is set to Auto, the
Fishfinder will acquire bottom readings as needed (within the capacity of the unit). When Max
Depth is set to match your fishing maximum depth, your Fishfinder will not attempt to acquire
sonar data below that depth, so more detail will be shown on the screen.
NOTE:
If the bottom is deeper than the Max Depth setting, the digital depth readout will flash, indicating
that the Fishfinder cannot locate the bottom.
