Garmin Sonar Readings Show Differently From One Panoptix LiveScope System to the Next

Often users compare the setup of sonar equipment, and it doesn't always look the same on display. Some settings are chartplotter specific, and others are sonar specific. Settings can differ between units and software versions. Below is a list of settings to look, compare and adjust. See the owner's manual for steps on sonar settings Finding the Owner's Manual for a Garmin Device.

Local to the LiveScope™ system (GLS™ 10 sonar module)

• Range

• Transmit On / Off

• TVG
