6.1 Pull out the rubber stopper, adjust float 
so that it is18 to 22 cm from the sensor, or 
at  your  desired  depth.Replace  the  rubber 
stopper by  pressing it  firmly into  the float. 
The Sensor float must be adjusted so that 
it  is  a  minimum  of  18  cm  away  from  the 
6.2 Toss  the  sonar  sensor  and float  assembly into water at your 
desired fishing location.To toss, place the sonar sensor and float in  
your  hand,  and  pitch underhand.  Do not throw the sensor by the 
cable as this will cause unrepairable damage. Before  tossing,  be  
certain that the cable is free from tangles and is not wrapped around 
6.3 Your fish finder includes a combination 
adapter,  mounting  bracket  for  the sonar 
sensor.The Adapter includes mounting taps 
so that you can attach it to any flat surface 
or boat hull and appropriate rod, The Adapter 
is  removable   and  adjustable  up  to  180 
6.4 Use a pole to guide the sonar sensor to a desirable position or 
add floats on the cable to float on the water.
NOTE:*Incorrect  to use : Do not allow the cable to  sink  to the 
bottom as it may become entangled  in debris. 
* The  float  can  be  removed as  follows, If  you do not need it, 
cutting  off  the  rubber  stopper  from the cable and sliding the 
safety strap and the float towards the plug and gently take it out 
7   FISHING AT THE BOAT OR ICE
7.1.1 Toss the sensor and float into the water as per the previous instructions.
7.1.2 Attach the adapter to the boat hull using the mounting tabs.
7.1.3 “shoot –Thru” the hull of a boat.
Place the  sonar  sensor in 1 inches of water against the hull bottom. 
Or coat the face of the sonar sensor with  petroleum jelly and press it 
against the hull bottom with a twisting motion.
7.1.3if it still doesn't work on all hulls and you may have to place the 
sensor directly in the water for proper operation.
NOTE: If depth readings appear as "---" while using one of these 
methods, place the sonar sensor directly  in  the water to verity 
that the fish finder is operating properly. If  it operates properly 
while directly in the water, reposition the sensor in a new location 
in the hull, and repeat the methods in above 
To achieve the best performance for ice fishing, it is highly recommended 
that you 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. Clear away  snow to expose the ice surface, making 
sure the surface is smooth. Place a small amount of liquid water on the 
ice and  set the  sonar sensor on the water, allowing the unit to freeze 
If there are any air  pockets between the sonar senor and ice, or air 
on  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 gently  tap 
sonar sensor at the base with your hand. If it will not come loose, 
spray a small amount of water on the ice surface around the base  
and repeat above step until the sonar sensor is easily removed. 
Never use a blunt to strike the sonar sensor as this  may cause 
damage to the sensitive internal electronics.
* Cold weather is extremely hard  on the electrical components  
within the display housing.  It is suggested  that  you  keep  the  
unit in temperatures above -17 degrees Celsius during operation.
*Remove  the  batteries  from  the  fish finder to prevent battery 
leakage and corrosion.Clean  the  sonar  sensor and cable with 
fresh water and dry-off before storing .Do not submerge and/or 
spray the fish finder screen/housing with water or use chemicals

Sonar technology is based on sound waves. 
The system uses sonar to locate  and define 
structure,  bottom  contour  and  composition, 
as  well  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; it then uses the reflected signal 
to interpret location, size, and composition of 
This    amazing  product    is    especially 
designed for amateur and professional
fishermen alike,  to findout the  location 
of fish and depth of water.The unit can 
be used in ocean, river or lake  and   is 
fantastic for datecting schools of fish in 
Using amazing and innovative technology, this portable fishfinder is 
the ideal toolto bring the fish toyou!

If the  finder determines that sonar has detected a fish,the display will 
show a  fish shaped icon. It can detect large fish and small fish.The first  
column of  fish indicators on  the  right  of the display shows the most 
current information. This  column  is then moved to the left as a new 
reading is displayed Fish icon moved in every 5 seconds.
The  depth  readout  on  the  top right, will appear after the power is 
turned ON and the sonar sensor is placed in water. The depth meter 
will indicate”---” if the depth exceeds these parameters. 
NOTE: This reading may also occur in water 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. 
Keep  this  in  mind when using the fish finder, as the smallest 
bubble between the sonar sensor and the water, will cause the 
unit not to operate correctly.
NOTE: The fish indicators move away from the right to the left 
at  a  constant    speed.  This  motion  in  no  way  reflects  actual 
Use the fish Depth lndicator to
measure the fish’s depth from 
the sonar sensor.This can  be 
done  by  dividing    the  depth 
reading  by  10.  This  number 
represents  the  value  of  each 
(Example, the depth is 20 m, the fish symbol appears in the 5th box 
from the top. This means the fish is 10 m from the surface)
The display indicates the presence of short weeds by turning on the 
smallest Weed indicator (a) Moderately tall  weeds are depicted by 
turning  on  the second Weed indicators(b) Tall weeds are depicted 
by turning on the third Weed indicator(c)
One Rock lndicator  identifies  limited structure(d) You would most likely 
find a small rock, a small pile of rocks, or uneven bottom contour. 
This is not a bad place for hiding fish, but due to the limited amount 
of strucrure, there may not be a lot.
Two  Rock  lndicators  identifies  a  considerable  amount of bottom 
structure, but scattered(e) A  considerable  amount  of  time  needs  
to be spent fishing this area  as  each piece of  structure  could  be 
hiding a prize catch.Three Rock lndicators indicates a large amount 
of bottom structure in a confined area. This  bottom  may consist of  
a large rock(s), stump(s), tree(s), or a ledge(s)(f)
