How Does Sonar Work
Sonar technology is based on sound waves.
The system uses sonar to locate and define the structure,
bottom contour and composition, as well as depth directly
below the transducer. The transducer sends a sound wave
signal and determines distance by measuring the time
between the transmission of the sound wave and when the
sound wave is reflected off an object, then it uses the
reflected signal to interpret location, size, and composition
of an object.

Installation of the transducer
1) For boats like Carp Madness, Anatec Monocoque, you need to drill a
hole on the boat bottom to fix the transducer.
2) For boats of BearCreeks, Carplounge, Waverunner, Vegaboat,
Carpboat, Anatec catamaran etc, there is a transducer groove on the
bottom. So, you only need to simply match the transducer to the boat
with a rubber.

Installation of the antenna and wiring
1) Drill a hole (5mm diameter) on the selected position. Only in case the
hole is not yet there.
2) Screw down the wisher and nut from the feeder cable, then hold the
cable through the hole from inner housing, and tighten the nut by a
wrench.
3) Screw the antenna on the boat.
4) After the installation is finished, please connect the parts (transducer,
antenna, battery) to the CCU. Then fix the CCU on the inner side of
the boat.

Powering
Please note: overvoltage may burn the elements in the device!
Below you can see the voltage range of the most popular batteries in the
market:

Using instruction
1) BC131 can be used by being fixed to a
remote control.
2) BC131 can be also used by being fixed
to a tripod.
Please note: make sure the antenna is tightened on the boat, otherwise
the R/C distance will be greatly shortened.

Key Functions
What is on the display

7
Sonar setting
In most cases, the default setting is enough. However, in some situations, to
get a better user experience, you need to adjust the menu setting.
oSensivity
Determines how echoes will be displayed on the screen.
Increasing the sensitivity will let you see more details on the screen. In deep
water, it is better to increase the sensitivity, whereas in the shallow it is
recommended to decrease the sensitivity.
oFish ID. Sens.
Fish ID. Sens. lets you adjust the threshold of fish size on display.
Selecting a higher setting allows any weak returns to be displayed as fish,
which is helpful especially when you are intending to find smaller fish species
or bait fish.
Selecting a low setting will prevent weak sonar returns being displayed as fish,
which will be very helpful when you are seeking large species of fish.
oGain
The gain controls the sensitivity of the hardware receiver.
A higher gain makes the sonar more sensitive to echo returns, allowing it to
display weaker targets. If the gain is set too high, the image might be cluttered
with some background noise.
Please note: when set in [shallow water mode], the [Gain] option will be
disabled. It is used to get a better sonar performance in shallow water.

Menu List
Sonar
Sensitivity
Controls the level of details shown on the display.
Fish ID. Sens.
Adjusts the threshold of fish size display. Higher setting allows
weak returns to be displayed as fish, while a low setting will
prevent weak returns from being displayed as fish.
Surface Clarity
Reduces the surface clutter by decreasing the sensitivity of the
receiver near the surface.
Gain
Controls the sensitivity of the hardware receiver. A higher gain
makes the sonar more sensitive to echo returns.
Shallow mode
Used to get better sonar performance in shallow water.
Display
Units
Set the units of measure for depth or temperature related
readouts.
Depth Range
Determine in which proportion the bottom will be displayed on
the screen.
Depth Offset
Adjust the digital depth readout to indicate the depth from the
waterline.
Color Invert
Invert the color of sonar image.
Chart Speed
Control how fast the sonar information moves across the screen.
Contrast
Get yourself a suitable display when operating the unit.
Alarm
Shallow Alarm
Makes sounds when the depth becomes equal to or less than the
menu setting.
Fish Alarm
Makes sounds when the fish finder detects what it determines to
be a fish.
CCU Alarm
Voltage
Makes sounds when the input battery voltage of the transmitter is
equal to or less than the setting.
System
Beeper
Set whether the sonar unit sounds a tone or not when a
key is pressed.
Language
Select the display language for menus.
Back light
Adjust the brightness of backlight.
Load default
Used to restore original factory setting.
Simulator
Used to let you practice using the Fish finder as if the
boat was on the water.
System info
