4. Connect the fish finder via USB cable
What to do if the computer does not see the fish finder?
If the device isn't detected, try replacing the USB cable with a shorter or higher-quality one. Also, check Windows Device Manager—it might need to install CH340 or CP2102 drivers, which are commonly used in similar electronics.
Common errors and how to fix them
During the update process, users often encounter various errors that can halt the process. One of the most common issues is the message "Connection Lost." This usually indicates a poor signal or a low battery. In this case, move the phone closer and connect the fish finder to an external power source, if the device supports it.

This is necessary to signal processing algorithms Correctly display the bottom topography and fish in specific water conditions. Don't ignore this step, as it directly impacts image quality.
Go to the settings menu and select the type of water: river, lake, or sea. Adjust the transducer sensitivity. Too high a sensitivity can create a lot of noise, while too low a sensitivity can hide small fish. Experiment with these settings in a familiar area of water.
- 🎣 Adjust the scanning frequency depending on the depth.
- 🌡️ Calibrate the temperature sensor if it is built into the case.
- 🔋 Check the battery charge display and adjust warning thresholds.
⚠️ Attention: After a major firmware update, the menu structure may change. Don't panic if you can't find a familiar function—carefully review the new sections or refer to the online manual.
Benefits of new software versions
Manufacturers regularly release updates for a reason. Each new version firmware brings stability improvements, power optimization, and new features. For example, the latest versions often feature improved target separation algorithms, allowing you to see fish close to the bottom.
