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 chang
e 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 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).
T
o 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 1500 feet, 3 to 500 meters [International Models Only],
Default = AUTO)
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)
Transducer Select
Transducer Select allows you to select which
transducer you want to use (the 700 Series™ Fishing System comes with a
DualBeam PLUS™ transducer, and also supports the optional-purchase
QuadraBeam™ and WideSide® transducers.)
T
o change the selected Transducer:
1. Highlight Transducer Select on the Sonar Main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the transducer
selected. (DualBeam, QuadBeam, WideSide, Default = DualBeam)
