SENSITIVITY
There are 5 user selectable sensitivity settings to choose
from. It greatly depends on the clarity and depth of the
water. Very clear water allows for a moderate sensitivity
setting. Conversely, dirty water requires a higher
sensitivity setting to target detail but will increase the
irritating false readings. Targeting deep water fish
generally requires higher sensitivity, especially in dirty
water. Salt and brackish water also require a
comparatively higher sensitivity setting. As the sensitivity
is enhanced, smaller details show on the screen (but
trash & debris might be detected as fish). The clearer the
water, the less sensitivity needed to get accurate details
and vice-versa.
BACKLIGHT
Turning the backlight feature ON will keep the screen
illuminated all the time. But it will greatly reduce the

5
battery life, so it’s suggested to only turn it on during low
light conditions.
When the backlight feature is set to OFF, the backlight will
only illuminate for 3 seconds whenever a key is pressed.
FISH ALARM
An alarm sounds when a group of fish are detected. The
alarm feature could be turn off if you prefer quiet fishing.
BATTERY SAVE MODE
When the Battery Save Mode is ON, the fish finder will
only send a sonar pulse every 3 seconds, instead of 3
sonar pulses every one second. This mode only updates
the display every 3 seconds and should not be used while
actively targeting fish. It’s useful for monitoring changes in
depth and bottom contour in 3 second intervals. The
screen can be refreshed by pressing the POWER Key.
UNITS OF MEASURE FOR DEPTH
1. Press and Hold ENTER key for more than 5 seconds.
The display will flash the current unit’s setting next to the
depth readout.
2. Press ENTER/SET UP key to select the unit of
measure (FT or M). The selected unit of measure will
blink.
3. The screen will automatically return to normal operation
after 5 seconds if no keys are pressed.
Depth Readout
The depth readout on the upper right corner of the screen
will appear after the power is turned ON and the sonar
sensor is placed in water between 2 feet and 328 feet (0.6
to 100 Meters). If the depth exceeds these range, the

6
depth readout will indicate “---”.
The reading “---”may also occur in water that is extremely
dirty, or where there are heavy silt or mud bottoms. Sonar
is a sound signal that travels through water. Sonar will not
travel through air. So the smallest air bubble between the
sonar sensor and the water will cause the unit to operate
incorrectly.
Note: The depth is measured from the sonar sensor, not
the float.
Fish Location
If the fish finder determines that sonar has detected a fish,
the display will show a fish shaped icon. The first column
of fish indicators on the right of the display shows the
most current information. This icon is then moved to the
left as a new reading is displayed. This motion in no way
reflects actual movement of the fish.
Fish Depth
How to figure out the depth of the
fish? This can be done by dividing
the depth reading by 10.
For Example: The depth is 200.0
feet, the fish icon appears in the 5th
box from the top. This means the
fish is 100 feet from the Sonar
Sensor.
Weeds Indicator

indicator A.
B. Moderately tall weeds are depicted by turning on the
indicator B.
C. Tall weeds are depicted by turning on the indicator C.
Rock Indicator
ABC
A. Sandy or muddy with no rock, debris or contour.
B. Moderately pile of rocks, or uneven bottom contour.
C. large pile of rocks or trees or ledges at the bottom.
How the Fish Finder Finds fish?
The system uses sonar to locate and define
structure, bottom contour and composition,
as well depth directly below the transducer.
It transmits a sound pulse from the sonar
sensor, and then measures the time it takes
for the echoes to return to the sonar sensor.
Different objects in water echo the pulse at
a different intensity. The built-in computer
then organizes all of this information and
shows it on a display screen.
SONAR SENSOR FLOAT
The Sonar Sensor float must be adjusted.
Pull out the rubber stopper. Adjust float so that it is 7(a
minimum of 7 inches) to 10 inches from the sensor, or at
your desired depth. Replace the rubber stopper by
pressing it firmly into the float.

Note: In calm water, the sonar sensor can be
set at a level which will provide the maximum
amount of sonar coverage. In rough water, the
sonar sensor may need to be lowered into the
water further to provide stabilized readings.
USING THE FISH FINDER WITH FLOAT
1. Place the sonar sensor and float in your hand, and toss
underhand. Do not throw the sensor by the cable as this
will cause irreparable damage.
2. Use a pole to guide the sonar sensor to a desirable
position
3. Add a float kit on the cable to allow the cable to float on
top of the water.
4. Neatly wind up the excess cable.
Note: 1. If you do not have a need for the sonar sensor
float, it can be removed. 2. Do not allow the cable to sink
to the bottom as it may become entangled in debris.
USING THE FISH FINDER WITH ADAPTER
Your fish finder includes a combination Side-Scan
adapter & mounting bracket for the Sonar Sensor.
A. The Adapter includes mounting bracket so that you can
attach it to any flat surface or boat hull.
B. The Adapter is removable and adjustable up to 180
Degrees.

FISHING FROM A BOAT
There are 3 methods that the fish finder can be used from
a boat:
1. Toss the sensor and float into the water as per the
previous instructions.
2. Attach the Side-Scan Adapter to the boat hull using the
mounting tabs. Please keep in mind that while using this
method, the fish finder is unable to function properly at
boat speeds over 5 mph.
3. Attach the sensor to a handle, lower the sensor into the
water.
Note: The Sonar Sensor should be placed in water.
ICE FISHING
To achieve the best performance for ice fishing, you
should cut a hole through the ice and place the sonar
sensor directly in the water. If you would like to check the
area for depth or fish before cutting the hole, please follow
steps.
1. Clear away snow to expose the ice surface. The ice
MUST be clear, free from air bubbles, voids, cracks, etc.
2. Place a small amount of liquid water on the ice and set
the sonar sensor on the water, allowing the unit to freeze

10
to the ice.
3. If there are any air between the sonar sensor and ice,
or the water below the ice, the unit will not work properly
and will require you to try another spot, or cut a hole in the
ice to use.
Note: To remove the sonar sensor from the frozen ice,
spray a small amount of water on the ice surface around
the base of the sonar sensor and gently tap the sensor
until the sensor is easily removed. Never use a blunt
object to strike the sonar sensor as this may cause
damage to the sensitive internal electronics.
STORING YOUR FISH FINDER
1. Remove the batteries from the fish finder before storing
to prevent battery leakage and corrosion.
2. Clean the sonar sensor and cable with fresh water and
dry off. Do not submerge or spray the fish finder screen
with water.
3. Never leave the fish finder in temperatures over 113°
Fahrenheit (45° Celsius) as the extreme temperatures
can damage the electronic components.
4. Keep the unit in temperatures above 14°Fahrenheit
(-10°Celsius) during operation. The sonar sensor cable
becomes very stiff under cold conditions. So do not wind
or unwind the cable in temperatures below 32°Fahrenheit
(0ºCelsius).
