From the LiveVü Forward or FrontVü sonar view, select Options.

Gain

Controls the level of detail and noise shown on the sonar screen.

If you want to see the highest intensity signal returns on the screen, you can lower the gain to remove lower intensity returns and noise. If you want to see all return information, you can increase the gain to see more information on the screen. This also increases noise, and can make it more difficult to recognize actual returns.

Depth Range

Adjusts the range of the depth scale.

Allowing the device to adjust the range automatically keeps the bottom within the lower portion of the sonar screen, and can be useful for tracking a bottom that has minimal or moderate terrain changes.

Manually adjusting the range enables you to view a specified range, which can be useful for tracking a bottom that has large terrain changes, such as a drop-offs or cliffs. The bottom can appear on the screen as long as it appears within the range you have set.

Forward Range

Adjusts the range of the forward scale.

Allowing the device to adjust the range automatically adjusts the forward scale in relation to the depth. Manually adjusting the range enables you to view a specified range. The bottom can appear on the screen as long as it appears within the range you have set. Manually reducing this option can reduce the effectiveness of the FrontVü Alarm, reducing your reaction time to low depth readings.

Transmit Angle

Adjusts the focus of the transducer to the port or starboard side. This feature is available only with RealVü capable Panoptix™ transducers, such as the PS31 transducer.

Transmit

Stops the active transducer from transmitting.

FrontVü Alarm

Sets an alarm to sound when the depth in front of the vessel is less than the specified value (Setting the FrontVü Depth Alarm). This is available only with Panoptix FrontVü transducers.

Sonar Setup

Adjusts the setup of the transducer and the appearance of the sonar returns.

Edit Overlays

Adjusts the data shown on the screen (Customizing the Data Overlays).
