Noise Filter (Advanced); Max Depth (Advanced) - Humminbird 1100 Series Operation Manual

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 controls the maximum depth of operation. When Max Depth is set to Auto, the
Fishing System will acquire bottom readings as needed (within the capacity of the unit). When
Max Depth is set to match your fishing maximum depth, your Fishing System 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 Fishing System cannot locate the bottom.
