Noise Filter

(Advanced)

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 Noise Filter menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).

NOTE: The Off setting removes all filtering; Low, Medium and High settings add progressive filtering of the sonar returns. In some deep water situations, the High setting may actually hinder your unit’s ability to find the bottom.

To change the Noise Filter setting:

1.Make sure you are in Advanced User Mode, then highlight Noise Filter on the Sonar main menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Noise Filter setting. (Off, Low, Medium, High1, High2, High3, Default = Low)

Max Depth

(Advanced)

Max Depth adjusts the maximum depth of operation. The performance of your 100 SeriesTM Fishing System can be tuned to the maximum depth you will be fishing in by setting the Max Depth. When a maximum depth is set, your 100 SeriesTM Fishing System will not attempt to acquire sonar data below that depth, thus increasing overall performance. When Max Depth is set to Auto, the 100 SeriesTM Fishing System will acquire bottom readings as needed (within the capacity of the unit). If the bottom is deeper than the Max Depth setting, the digital depth readout will flash, indicating that the 100 SeriesTM Fishing System cannot locate the bottom. The Max Depth menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).

To change the Max Depth setting:

1.Make sure you are in Advanced User Mode, then highlight Max Depth on the Sonar main menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Max Depth setting. (AUTO, 10 to 600 feet, 3 to 240 meters [International Models only], Default = AUTO)
