You can experience the XFishFinder echo sounder application before you get to the pond. To do this, run it and click the buttons Menu - Demonstration of work.


Connect via USB OTG cable to XFishFinder device

To connect a XFishFinder device to your smartphone or tablet, use a MicroUSB OTG to MiniUSB adapter (included)

Connect via BlueTooth to a XFishFinder USB OTG + Bluetoth device

On your smartphone or tablet, turn on the BlueTooth module and select the XFishFinder device from the available BlueTooth devices. Wait for the connection.

Start the XFishFinder application, then the echo sounder will be ready for use immediately. In some cases, if you need to connect the echo sounder to the device manually, press to do so. Menu – Device - Connection, then select the type of connection.


Sound waves are the foundation of echolocation technology. This technology allows you to determine the topography, the structure of the bottom and the depth directly below the wireless sensor (transducer). The transducer sends a sound wave and determines the distance to the day by measuring the time between the transmission of the sound wave and its reflection from the object. The echo sounder processes the reflected signal and determines the location, size and type of the object.

Main Screen

Open the XFishFinder application. You will see a map screen and an echo sounder.

Remember that some interface details may differ on different smartphones or tablets

Image of the bottom

Interpreted sonar data is displayed on the main screen. Depth and bottom displayed in the lower part of the screen.

Sonar reflects only what is under it. The later the information was collected, the more to the right it is on the screen. The current data is displayed on the edge of the screen, in the rightmost part of the display. The view scrolls to the left as new information is received from the echo sounder.

The bottom of the reservoir always reflects a strong signal, therefore it is depicted as a continuous, intensely colored line running at the bottom of the screen.

Vegetation information (algae at the bottom of the pond) is displayed in green.

Echo Sounder XFishFinder has signal interpretation technology. It displays fish and bottom structure. Large flocks of fish or objects close to the bottom can affect the readings of the depth of the reservoir.

You can track fish by viewing current sonar data using the fish icon. Fish icons are displayed depending on the size of the fish.

Remember that fish classification depends on various characteristics. The weight of the fish is only one of them, therefore the size of the sign of the fish may not always correspond to its size.

Troubleshooting Tips and Tricks


To establish a connection, place the sonar sensor in the water at a distance of no more than 5 meters from yourself.

Restart the application or smartphone if you cannot establish a connection for a long time.

Hold the smartphone correctly

It’s best to hold a smartphone or tablet in your hand or use a special mount to a fishing pole. If the smartphone is in your pocket or on the ground, this can cause connection problems.

The case for a smartphone or tablet should be made of lightweight plastic. Metal covers or covers made of thick plastic will not transmit Bluetooth radio.

Avoid interference

Connect the XFishFinder to no more than one sonar sensor!
