10. User Tips
- Water Clarity: For best results, use the fish finder in clear water. Murky or heavily sedimented water will reduce visibility.
- IR Light Usage: The infrared lights are excellent for dark or deep water. However, in very clear, shallow water, they might reflect off particles and reduce image clarity. Experiment with turning them on/off to find the best setting.
- Cable Management: Use the provided camera holder and float to manage the camera's depth and orientation effectively. This helps in targeting specific areas or observing fish behavior.
- Battery Conservation: If not actively viewing, consider turning off the monitor's backlight to extend battery life, especially during long fishing trips.
- DVR Function: If your model has DVR, remember to regularly check and clear your TF card to ensure you have enough space for new recordings.
