Overview
BC202 intelligent sonar fish finder is a directional research and development,
suitable for its matching fishing boats high precision and sensitive detection of
river, river, lake, sea and other water environment.This fish finder can also
provide with the depth of the bottom, bottom contours, water temperature,
density of fish or the depth of fish and other parameters for your reference.
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.

Current Signal Chart (Real-time Signal RTS)
The current signal chart box is to display the strength of the latest echo in
horizontal lines at the far right of the display screen. The wider the horizontal
line indicates the stronger the signal, and the depth of the echo refers to the
depth scale.

Sonar Menu Components Settings
o
Sensitivity
Settings: “Auto”, “1%” to “100%”
Sensitivity controls the unit´s ability to pick up echoes. If you want to see
more details, try increasing the sensitivity, a little at a time.
Sonar menu
Setup menu Advanced menu

15
Press the menu key to select "sonar" menu to enter the sensitivity sub-menu.
Optional settings:"1%"to"100% or "Auto".
Users can filter the sonar echo signals by adjusting the sensitivity until the
signal information they need is displayed on the screen. If you want to see
more details, try increasing the sensitivity, a little at a time. At high sensitivity
value, a lot of underwater noise will also be displayed on the screen. If you
don't want to see these underwater noises, you can reduce the sensitivity
value to filter them. When the sensitivity is set to "Auto", the system will
automatically set the sensitivity value according to different depths of water, so
that the users do not need to manually adjust the sensitivity
There are 1%~100% sensitivity levels in the menu for users to choose.
Sonar fish finder is a device that can emit ultrasonic waves and analyze
reflected waves. When the fish finder emits sound waves in the water, all
objects whether they are large, small, soft or hard, will generate a reflection
wave. Larger or harder objects sometimes generate multiple reflection waves.
So it needs a "sieve" filters out unnecessary information. The sensitivity here is
the "sieve pore" of the "sieve". The higher the sensitivity, the "smaller" the
"sieve pore".
Increasing the sensitivity is equivalent to reducing the "sieve pore", so there will
be more stuffs left on the "sieve" (the information displayed on the screen),
which may cause the information displayed on the screen to be cluttered.
Decreasing the sensitivity is equivalent to increasing the "sieve pore", so there
will be less stuffs left on the "sieve"(the information displayed on the screen),
and the system will filter out some information to make the display screen
more concise. But be aware that what you filter out may be also important
information.
Therefore, it is important to choose the appropriate sensitivity value and the
depth range. In general, we recommend that you increase the sensitivity when
the water is deep or clear. You can reduce the sensitivity when there are
more impurities or turbidity water or there is in shallower water to reduce
some false detection results.
When there are many fish, you can also use this function to distinguish big and
small fish. Decrease the sensitivity, the "sieve pore" will be enlarged, then the
objects with weak reflection waves will be filtered out, and the rest are
relatively large fish.

16
Higher sensitivity Low sensitivity
o
Depth Range
Select “Auto” to have the unit automatically select the Depth Range, the
bottom signal is automatically placed in the lower half of the screen.
Select specific value to lock the depth range to a specific setting.
Press the menu key to select "sonar" menu to select the depth range option
by the up and down keys. Press the ENT key and then press up and down
keys to select Settings: "0-9ft" to "0-240ft", "Auto" ("0-3m" to "0-80m", "Auto").
There are 8 setting values in this menu.
When the depth unit is set to "FT" (feet), the 8 setting values are: "0-9FT",
"0-15FT", "0-30FT", "0-60FT", "0-90FT", "0-120FT", "0-240FT", "Auto".
When the depth unit is set to "M"(meter), the 8 setting values are: "0-3m",
"0-5m", "0-10m", "0-20m", "0-30m", "0-40m", "0-80m" "Auto".
When the depth range is set to a fixed value, the screen adjusts to the
corresponding display range according to the setting value. content beyond
the setting range will no longer be displayed.
Please Note:
In manual operation, if the depth is greater than the depth range setting, the
bottom will not be visible on the screen. You can select “Auto” to return to
automatic operation.

17
o
Upper and Lower Limit
Settings: “0ft” to “231ft”
(“0m” to “70m”)
Settings: “9ft” to “240ft”
(“3m” to “80m”)
Changing the upper and lower limits gives you far greater control over the
depth range. This feature lets you “zoom in” the display in almost unlimited
combinations.
o
Fish Symbols & Depth
Settings: “On/On”, “On/Off”, “Off/Off”
"On/On": shows both the fish symbol and
the depth of the fish
"On/off": shows only the Fish Symbols and
not the depth of the fish.
"off/off": sign and the depth of the fish are
all not displayed.
When the Fish Symbols and the display of
fish depth are set as "on", the system will
analyze the echo signal and display different sizes Fish Symbols according to
the strength of the echo signal and then displayed the corresponding depth
value above the Fish Symbols.

18
This product is a very powerful echo signal analysis system. Part of the water
noise, surface clutter and temperature variable layer can be removed by menu
setting, and then the rest of the signal information corresponding to display as
Fish Symbols. However, the system is also limited, and some situations cannot
be recognized, such as deadwood floating in water, air bubbles, garbage, etc.,
may also be shown as fish symbols.
The sonar system is not an underwater video system. It cannot visually display
fish and other floating objects, such as water plants, deadwood, air bubbles,
garbage, etc. The user needs to judge by the reflected sonar signal.
Please Note:
The sonar’s microcomputer is sophisticated, but it can be fooled. It can't
distinguish between fish and other suspended objects such as trotlines,
submerged floats, air bubbles, etc.
o
Depth Cursor
Settings: “On”, “Off”
The depth cursor consists of a horizontal line with a digital depth
box on the right side. The numbers inside the box show the depth
of the cursor.
You can move the cursor to any location on the screen, letting you
pinpoint the depth of a target.
o
Simulator
Settings: “On”, “Off”
The Simulator is a very powerful tool that
simulates on the water operation. Use the
Simulator to learn how to use your fish finder
before taking your boat on the water The
Simulator Indicator will be visible on screen
when Simulator is set to “On”.

Setup Menu Components Settings
o
Backlight
Optional settings: “10%” to “100%”
User can switch the Front light or adjust the brightness as needed.
When the screen backlight is set to turn on, (10%~100%), the background
light will always be on, which will consume a lot of power and reduce the
battery life. So you better use this feature only in low light.
The screen of this fish finder is clear viewing in direct sunlight, so the backlight
can be turned off when used outdoors during the day.
o
Volume
Settings: “High”, “Medium”, “Low”
Volume setting allows you to adjust the Alarm Volume so that you can select
the tone that you can hear best.
o
Units
Settings: “ft/°C”, “ft/F”, “m/°C“, “m/F“
o
Chart Speed
Settings: “10%” to “100%”
The chart speed is the rate echoes scroll across the screen. User can adjust
the chart speed as needed.
It is recommended that the chart speed should be set to the maximum so
that the reflected wave information can be updated in a timely manner.
