Water Type
(Advanced)
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
(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 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
(Advanced)
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 1000 feet or 3 to 330 meters
