Water Type
configures your unit for operation in fresh or salt water. 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. Also,
make sure that the Water Type is set accurately, especially in salt water, as this affects the
accuracy of deep water depth readings.
To change the Water Type setting:
1. Make sure you are in Advanced User Mode, then highlight Water Type on
the Sonar main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Water Type
setting. (Fresh, Salt, Default = Fresh)

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 FishFinder’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, High, Default = Low)

Max Depth
adjusts the maximum depth of operation. The performance of your
FishFinder can be tuned to the maximum depth you will be fishing in by setting the
Max Depth. When a maximum depth is set, your FishFinder will not attempt to
acquire sonar data below that depth, thus increasing overall performance. When Max
Depth is set to Auto, the FishFinder 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 FishFinder 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 800 feet or 3 to 260 meters [
