1) There are 2 charging cords in the package, the Micro
USB for the host and the DC for the sonar sensor.
2) When the battery indicator icon on the screen flashes,
please stop using the fish finder and charge the fish finder.
3) When the host is charging, the indicator light is red. It
will turn green if the host is fully charged. When the sensor
is charging, the indicator light is red. It will turn off if the
sensor is fully charged.
4) When the sensor is out of water, it is off and will NOT
connect with the host. If you would like to check the
sensor's battery status from
the screen, you need to put
the sensor in water first.
Note: Please use 5V USB
charger (not included). The
cover of the sensor should be
removed when charging, and
should NOT be removed
when working.

4. Attentions
1) The host is not waterproof. If water splashes on the host,
please dry it immediately.
2) The sensor is supposed to float on water when working.
Please don’t drag it into water bottom, or submerge and
hold the whole sensor under water.
3) Its reading might be interfered with other high power
sonar device close to your sonar sensor.
4) If water wave is too strong, please protect the sensor
from crashing into rock. Otherwise it will cause irreparable
damage to the sensor.
5) The fish finder will only operate properly in open water
that is deeper than 2.6 feet.
How to Use the Sonar Sensor
1. How the sonar fish finder works
1) The system uses sonar to locate
and define structure, bottom contour,
and depth directly below the sensor.
It transmits sound pulse from the
sensor, and then measures the time
it takes for the echoes to return to
the sensor. Different objects in water echo the pulse at a

4
different intensity. The built-in computer then organizes all
of this information and shows it on the display screen.
2) Sonar usually determines there is fish when it detects
the air in fish swim bladders. That is also why the small
bubbles in water might affect the fish finder's performance.
3) The first column of fish indicators on the right of the
screen 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.
2. Sonar sensor
1) How to turn on the sensor
There are 2 pins on the sonar bottom, which are the
automatic switch of the sensor. The sensor will turn on
only when you toss it in water.
Note: Please dry water on the sensor after it is out of water.
Otherwise the sensor might keep working.

5
2) How to use the sensor
There are 2 small holes on the sensor. Tether the sensor
with fishing line (not included) and toss it into water. You
can use a rod to guide the sensor to a fix spot or use a
remote-controlled boat to send the sensor to the fishing
spot.
3. Application methods
1) Toss the sensor into water, drag it at a very slowly and
stable speed. It will display information of water under the
sensor, including water depth, bottom contour, and fish
location.
2) Toss the sensor into water, guide it to a desirable
position and let it undisturbed. It will float on water and
monitor submarine news in a real-time method.
Information will be automatically updated on the screen
once fish enter the sensor detection range.

2. Feature Setup (Preference Setting)
There 3 setting/menu pages (Sonar, Setup, and Senior).
Press Menu Key to enter and switch setting page.
1) Sensitivity
There are 20 levels of sensitivity setting for user 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 fish in deep water generally requires higher
sensitivity, especially in dirty water. Otherwise, the sensitivity
can be lowered in shallow 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).
Operation guide:

Frequently Asked Questions
1. It will not power on
Press and hold the power key for 2 seconds to turn on the
display unit. If the display unit does not turn on under
properly operation, please send your order number and fish
finder issue to venterior@yahoo.com for help.
2. Depth reading is “---” or incorrect
1) Ship motor or other high power sonar fish finder close to
the fish finder will interfere with the fish finder’s sonar and
cause incorrect reading.
2) Oil, dirt would adhere to the surface of the sensor and will
affect the sonar sensor's performance. Please make sure

14
the surface of the sensor is clean.
3) Please make sure the water is within the depth range of
2.6Ft/0.8M to 164Ft/50M.
4) Suspended matter, muddy water, or extremely heavy
vegetation may also confuse the sonar and cause
misreading of depth.
5) Please make sure the sonar is not out of power and floats
on water in peace. If water wave is too strong, the depth
reading might be incorrect.
6) Please make sure the sensor is verticallydownward.
7) Please make sure the temperature is above -10℃/14℉.
8) When fishing on ice or “shooting-through” the hull of a
boat, depth reading might be unstable or displays as “---” if
there is bubble under the sonar. Sonar will not travel through
air. So the smallest air bubble between the sensor and the
water will cause the unit to operate incorrectly.
3. It shows fish / It is not working in mypool
The fish finder will NOT function properly in a bath tub,
swimming pool, bucket, or any body of water that has hard
sides. It must be used in an open body of water to function
properly.
4. Is the displaywaterproof?

15
The display is not waterproof. Do NOT submerge or spray
the fish finder screen with water.
5. How long is the batteryduration (fully charged)?
It depends on the backlight level you set. It usually lasts
about 4-6 hours in continuous use. Reduce the backlight
level to extend battery life.
6. There are fish in water, but the fish finder shows
nothing.
The fish finder can only detect fish in detectable area (105
degrees beam angle under the sensor). And the fish finder
will not detect any objects that are closer than 2 feet from
the sensor. It is the blind area of sonar. If you’re fishing in
water that is less than 3 feet deep, it is recommended to
discontinue use of the fish finder. Besides that, the fish
finder might not be able to distinguish fish from weeds if fish
swimming too close to the water bottom.
7. False fish indications
Tall weed may cause false fish indications. If weeds grow
taller than 50% of the total water depth, the sonar will
mistake it for fish. Trash & debris may also result in false fish
indications. Adjusting the sensitivity setting to the lowest

16
level may reduce these false readings, but if they do not go
away, it is suggested that you discontinue use of the fish
finder under these conditions.
8. Will it work for ice fishing?
It can work for ice fishing. It is suggested to drill hole on ice
and put the sensor into the water.
9. How far do you cast it out?
The maximum wireless distance range is about 262Ft/80M.
10. Does it show the size of fish?
It displays fish symbol by 3 different fish sizes --- small,
medium, big.
11. How to make it more visible in bright sunlight?
The default setting of background is Black. Please change
the background to white in bright sunlight. White
background will makethe readout more visible.
12. Can this be mounted to the boat?
There are 2 holes in the sensor for you to tether with fishing
line. You can mount it to your boat. Please make sure it is

17
floating vertically downward.
