Host battery installation steps:

Open the battery cover

2. Install 4 x 7 batteries.

3. Push the battery cover back until it is completely tight.

Ps: Pay attention to the battery indicator in the battery box, please follow the signs inside.

Probe charging steps:

1. Unscrew the probe to have a charging contact point and insert the charging head.

2. When the battery level is lower than 3.2V, the probe battery indicator on the main unit display will flash. Indicates that the fish finder should stop working and start charging.

3. If there is water in the main unit or probe, please do not recharge it to avoid adverse consequences.

Introduction to sensor usage:

Method 1: Connect the fishing line to use the rod

Method Two:

1. Use the remote control boat to send the wireless sensor to the fishing spot, and attach the sensor, buoy and fishing lure to the end of the fishing rod and put it into the water.

2. When the sensor enters the water, it will use the conductivity of the water, turn the sensor on and off, and you can start fishing.

3. The sensor injects ultrasonic waves into the water, and the central processing unit of the host receives the signal collected by the sensor through the radio for filtering and analysis.

4. The CPU will compile the results and display them on the display.

5. The latest data is on the far right of the display and disappears to the far left.

6. The bottom of the display shows the underwater structure. The depth of the water, the temperature, and the fish mark are displayed on the display.

Note on the use of the sensor:

1. When the sensor is working, do not touch the bottom of the sensor with your hand. Otherwise, the test result of the product will be wrong. It will even damage the components inside.

2. If you want to take the working sensor out of the water, you can grab the end of the sensor housing and remove it.

2. Our products are normally used for a long time, but in the water, due to the fluctuation of the waves, the sensor may be impacted, causing it to hit the reefs and other objects, causing damage to the sensor.

3. Due to the physical properties of the ultrasound itself, we recommend not using the product when the water depth is below 0.8 m.

Remarks:

The rope color is random, usually black, or grey.

Notes:

Please allow 1-3mm differs due to manual measurement.

Due to the different display and different light, the picture may not show the actual color of the item.Thanks for your understanding.
