3. When connected to external CHIRP sonar
modules (excluding DownVision TM ) and external
traditional sonar modules (excluding legacy) you
can select an auto TVG mode,
Noise Filter
The Noise Filter is available on DownVision TM sonar
modules. The Noise Filter reduces the amount of
clutter displayed on-screen by varying the gain
throughout the column of water.
The Noise Filter can be set to automatic or adjusted
manually:
• Automatic — In Auto mode the Noise Filter is set
to 20%.
• Manual — You can adjust the Noise Filter
manually, between a value of 0% to 100%.
– A low value decreases the depth at which the
filter is applied.
– A high value increases the depth at which the
filter is applied.
The new values remain set even when you switch
off the display.
Adjusting the Noise Filter
Follow the steps below to adjust the Noise Filter.
From the Fishfinder application:
1. Select
Menu .
2. Select Sensitivity Settings .
3. Select Noise Filter .
The Noise filter slider bar control is displayed.
4. Adjust the Noise Filter to the required value, or
5. Select the
Auto check box to switch to Auto
mode.
Note: The Noise filter can also be adjusted by
selecting the on-screen N. Filter control.
Color threshold
Color threshold determines the signal strength
below which targets are not shown. Traditional and
CHIRP sonar use different colors to determine signal
strengths whilst DownVision
TM uses monochrome
shading.
The Color Threshold setting is a global setting. When
the color threshold value is changed all Fishfinder
application panes on all networked multifunction
displays will share the same color threshold value.

A low setting would result in only the strongest colors
or lightest shades being displayed.
Adjusting the color threshold
The color threshold’s default value is 100%, you can
adjust this setting so that less colors / shades are
displayed.
From the Fishfinder application menu:
1. Select
Sensitivity Settings .
2. Select Color Threshold .
3. Adjust the color threshold to the required value.
4. Select
Ok to confirm setting and close the
numeric adjust control.
Power mode
Power mode controls the power level of the
transducer. Power mode can be set to automatic or
adjusted manually between 0% and 100%. Power
mode is only available on CHIRP, Traditional and
Legacy sonar modules.
• Auto — This is the default setting. When auto
is selected the sonar module automatically
determines the optimum setting based on the
current depth, speed, and (bottom) signal strength.
• Manual — You can adjust the power level between
in 1% increments. Lower power levels are
normally used in depth ranges less than 2.4 m (8
ft.) and higher power levels are typically selected
for depths greater than 3.7 m (12 ft.).
Adjusting the transducer power level
From the Fishfinder application menu:
1. Select
Sensitivity settings .
2. Select Power Mode .
The power mode slider bar control is displayed.
3. Adjust the slider bar to the required setting, or
4. Select
Auto to set automatic power mode.
