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 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. To change the Noise Filter setting: 1. Make sure you are in Advanced User Mode, then highlight Noise Filter on the Sonar main menu. 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 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 Fishing System will not attempt to acquire sonar data below that depth, thus increasing overall performance. When Max Depth is set to Auto, the 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 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). 54 531524-1_A - 717 & 727 Man_Eng. qxp 9/30/2006 7:24 PM Page 60 To change the Max Depth setting: 1.

The Water Type menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: In salt water, what would be considered a large fish might be 2 to 10 times bigger than a large fish in fresh water (depending on the type of fish you are seeking). The salt water setting allows for a greater range in fish size adjustment to account for this. [. . . ] TripLog: TripLog is a Humminbird® feature that provides an on-screen counter for Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to activate the feature. TripLog appears on the Big Digits View, and can be reset to zero through the TripLog menu. TrueArch®: TrueArch® is a Humminbird® feature that provides true fish arches, not artificial arches or symbols. Humminbird® units are capable of producing fish arches due to the wide 60° sonar beam of DualBeam PLUSTM, an extremely sensitive sonar receiver. [. . . ]
