WIRELESS FISH FINDER
OPERATION GUIDE
1 PRODUCT OVERVIEW
This amazing product is especially
designed for amateur and professional
fishermen alike, to find out the location
of fish , depth and bottom contour of
waler
The unit can be used in ocean, river or
lake and is fantastic for detecting
schools of fish in any particulararea.
Using amazing and innovative
lechnology. lhrs portable fish finder is
the ideal tool to bring the fish to youl
2 HOW SONAR WORKS
Sonar technology is based on sound
waves. The system uses sonarto locate
and define structure. bottom contour
and composition, as well depth directly
below thetransducer. The transducer
sends a sound wave signal and
delermines distance by measuring the
time between the transmission of the
sound wave and when the an object;
it then uses the reflected signal to
interpret location, size, and
composition of an object.

6. USING THE WIRELESS SENSOR
Uge the wlreless sonar sensor is
v6ry easy for user, just simply
attach the sensor to the end of
your fl8hlng llne and cast it into
the water es your normal float or lure.
A. front hol€
8.1 You can tie your fish reel line to the frontholeinthewireless
tranBduc6r. lf you want to use the wireless transducer as a stationary
float,useths sacond hol6toattach yourhook using a lighterweight
llno. but A obstaclo will brsak the lighter line easily, for this reason, we
sugge8tyou not to pull the lighterweight line if unnecessary.Slip line
technlquos are not recommended because will incre'ase the risk of
lo8lng th6 wlrels8s transducer. lf you do use the slip line method.
u8e a llghter welght lln6 aftsr ths lower stop, unable get back of the
wlreless transducar lf the lower line with hook breaks away.
6.2 You wlll lncroase tho rlsk of breaking your line if you use light test
pound llne on your roel. Ths transducer in water is positively buoyant.
Ths maxlmum amount ofwslghl for any attachment to the transducer
ls approxlmatsly 6 grams, and lncludes the combined weight of any
hook, line, weight swlvel/snap swivel and bait that is attached to the
wireless lransducer. ovor5.Tgwill submerge the wireless sonar
sensor, causing ths slgnal loss.
7.How to replace the CR-2032 battery
7.'l R€move the battery doorof thewireless sonarsensor, and press
ths lock-biock of the batt6ry holder and the battery will flip pls check
th€ picture.(fig.9, fig. 1 0)
7.2 Make sure that the o-ring in the battery compartment is present,
positioned correctly in the grooves, and free of debris before
16installing the battery door.

NOTE:The bottom of the wireless transducer should not bs handls durlr
soner operation, as this may cause physical discomfort and may result I
pereonal injury in the form of tissue damage. Handle the wlrelct
transducer only by the antenna tower when it has been in the water.
NOTE:Tne wireless transducer is not intended for use by children young
than 6years old without adult supervision as the transdu@r may reproSc
a choking hazard to small children.
NOTE:When ths fish finder receive the signal from wireless sensor th
signal indicato(f,1llll witt aisotay on ttre screen.The max RF distancc
the unit is 60 meters unless the water is smooth. The signal indicat(
will disappear if the distance between the fish finder and the wirEla
sensor over 60 meters. The wireless transducer has contacts that percohr
when the device is immersed in the water. These contacts turn on tl
sonar transmitter/recgiver and begin transmitting the sonar information vl
Radio Frequency to the display. The wireless transducer automatical
stops using power a few se@nds after being pulled out of the water
NOTE:Do not plae the wireless tEnsducer in a wet area when not in ut
as this will turn on the wirelesstransducerandshortenitsusablellft
Store the wireless transducer in a dry area when not in use to conssrui
powen Never place the unit in a wet area of a boat or on a metal surtrao
that could accidentally power it on.
NOTE:lf the unit was used in salt water,rinse it with fresh water bofot
storing it.
NOTE: lf the handheld device fails to receive signals from the wirelet
sensor, it will stop showing on the screen. ln any €se, if the handhel(
devie can not receive signals transmitted by ths sensor or the sensor ll
out of water for several seconds, the screen will not show fish and doptl
meter and sensor connect indicator until thesensoris placed inwatt
again and signals are restored.This machine is a products depending ot
line of sight. So the barrier between the handheld devie and the senso
can lead to signal loss.
NOTE:lnmrrect reading may appear in water areas with dspth less thf
0.7meter. Additionally, considering the sonsar physical charactsrs, w
suggest you avoid using the products in swimming pools or small-slz(

enclosed water areas. Dragging the sensor too fast can lead to signal lost.
With relatively quite water areas, this products is able to obiain a '160-feet
remote-control distance in max; with signifiaant fluctuations on water
surface, the distance may be reduces slightly. lfyou drag the sensor
or it floats out of the range,inconsistent signals or even no signals
will be transmitted to the handheld. lf nothing displayed, please be
sure the batteries positive and negative poles are correctly orienled
in the holder, also check if the batteries has enough power.
Maintenance for the handheld device
Many factors about anomalous operation have been tak6n into
consideration while designing this fish finder.This effort have ensured
that the product is able to work formanyyearsevenwithoutregular
maintenance. Follow these steps to ensure your fish finder continues to
deliver top performance.
1)lf the unit comes into contact with salt spray,use a softcloth
dampened in fresh waler then wipe the affected surfaces.
2) Don't use a chemical glascleaneron thesurface! Ohterwise, this
will scratch the surface. When cleaning the LCD protective lens,
use a chamois and mild cleaner. Don't wipe while dirt or grease is
on the lens. Be careful lo avoid scratching the lens.
3) Do notplace the unitin aclosed car! Thiswill lead tothe internal
electronics
Parts damaged for the high temperature in hot weather days.
Maintenance for the wireless sensor
1 ) Before store the wireless sensor, pls wipe the surface with a soft cloth
dampened with fresh water afier using the wireless sensor in salt water.
2) Rinse the wireless sensor botlom alloy pins with fresh water afier using
in salt water
3) After store wireless sensor out of the water for a long time, it will take
some time to wet it when retumed to the water. Small air bubbles can
cling to the surface of the wireless sensorandforecloseitnormal
operation. Wipe fie face of the sensor with a wet soff cloth to eliminate
them.
4) Do not place the unit in a car! This will lead to the internal electronics
parts damaged for the high temperature in hot weather days.
