3. The handheld host drop into the water.
3.How to install the battery
3.1The host battery installation steps are as follows:
1.Open the back cover of batters.
2.Install 4 “AAA” batteries. Be certain that the batteries compartment.
There are aligned as per the diagram within the battery house.
3.Slide the battery cover towards the top of the unit until it is completely
closed.
3.2 Inside the probe has a rechargeable polymer battery. If the battery is
no power, you can charge for it.

NOTE:
1. There are two ports of the charging line, USB port connects 5V DC
power supply,another connects the DC female.
2. When the probe’s battery is lower than 3.2V, the battery indicator
symbol on the host screen will twinkle. It means the probe should stop
working and need to charge.
3. If there is water inside, please don't charge, to avoid adverse
consequences, and it should be sent back to the factory to get
maintenance as soon as possible!
4. When charging, charging indicator (red) will be on; and the light will

4.Sonar Sensor Using Induction:
You can refer to the chart!
This product is designed with user-friendliness in mind. Attach the
sensor to the shing rod’s extreme and throw them into water as you do
with oat and baits. After switching on the main unit’s power on, you
are ready to fish. Sonar technology is used in the product, the sensor
transmits ultrasonic waves to the water, and the microprocessor will lter
and analyze the fed-back signals. The analysis result will display to the
screen after being compiled. The latest data is displayed on the very right
of the screen but disappears on the left. The water bottom contours are
showed in the middle as well as water depth, sh size, and location etc.
Attention:
1. While the sensor is work, do not hold it at the bottom; otherwise, the
testing results may be error or even damage to internal structures and
elements. To pick up the sensor working in water, please take hold of the
antenna post at the sensor’s top.

2. The sonar sensor is designed to work durably in normal service.
However, due to the wave of ups and downs in the water, it may impact
sensors or make it hit the rocks and other objects, which will result in
damages to the device. Therefore, for water areas with depth less than 2
foot (0.6m), we recommend that you avoid using the unit!
5 Applied mode:
5.1.Sonar Graphic Mode:
Fish nder renders real-time conditions of the water bottom with sonar
graphic. Throw the sensor into water, drag it slowly at a stable speed, and
you can view accurate information displayed on the screen, including
water bottom contour, structure, depth, sh location, etc.
5.2.Stationary Float Mode:
Throw the sensor to water and let it undisturbed. It will oat on the water
surface, monitoring submarine news in a real-time method. Information
will be automatically updated on the screen as soon as the sh enter the
sensor detecting area.
6.Sonar Sensor Introduction
6.1.The sonar sensor has two parts. One part is sonar, the other is RF.
Signal acquisition depends on sonar part. Signal communication
depends on RF part.
1.Power supply
The sonar sensor is supplied by a polymer battery. When the battery has
run out, you can recharge it. The method you can reference to the map.
2.Electronic switch
The sonar sensor’s bottom has two pins. It is the switch. When the sonar
sensor is thrown into water, the sonar sensor will work by using the
electrical conductivity of the water conduction. And you should store
5

it in a dry and insulated place after using. If you store it in a wet or
conducted place, the humidity or conductor will cause the sonar sensor
power on automatically. Please clean the sonar sensor with clean water
and dry it in the air before storing.
Sensor Working Theorem:
The sensor working theorem is the electrical conductivity of water.
6.2.Work process is as follows;
1. When the sensor is thrown into water, once the two pins touching
water, the sensor will begin working.
2.When the sensor is dropped out from the water, you can dry the
remained water from pin surface, the sensor will stop working
automatically.

6.3.Sonar Sensor Maintenance And store:
1. Do not place the sonar sensor in a wet area when not using, the
dampness may turn on the sensor itself automatically. The battery will be
depleted fast. Also avoid placing it on a metal board!
2. You should store it in a dry, nonmetal place! The place is far away
from any metal equipment.
3. Clean the water of the surface after use. Dry it in the air before store
it.
7.Display Interface:
