Frequently asked questions

How can I adjust the fish alarm sensitivity on my sounder?

To adjust the fish alarm sensitivity, you can access the "Sounder System Setup" menu and select the "Fish Alarm Level" option. From there, you can choose between "High", "Medium", or "Low" sensitivity levels to best suit your fishing conditions.

What does the "TVG" setting do on the sounder?

TVG stands for "Time Varied Gain". This setting compensates for the attenuation of ultrasonic waves as they travel through water, ensuring that fish schools of the same size appear with similar density on the display, regardless of their depth.

How can I set the depth and temperature calibration on my sounder?

You can set the depth and temperature calibration using the "Sensor Setup" menu within the "Sounder System Setup". The calibration values allow you to ensure that your sounder readings are accurate and reflect the actual conditions in the water.
