Setting the Garmin FrontVü Depth Alarm
The Garmin FrontVü depth alarm is a tool for situational awareness only, and may not prevent groundings in all
circumstances. It is the obligation of the vessel operator to ensure safe operation of the vessel.
This alarm is available only with Panoptix Garmin FrontVü transducers.
You can set an alarm to sound when the depth is below a specified level. For best results, you should set the
bow offset when using the front collision alarm
1 From the Garmin FrontVü sonar view, select Menu > FrontVü Alarm.
2 Select On.
3 Enter the depth at which the alarm is triggered, and select Done.
On the Garmin FrontVü screen, a depth line shows the depth at which the alarm is set. The line is green when
you are in a safe depth. The line turns yellow when you are going faster than the forward range gives you time
to react (10 seconds). It turns red and sounds an alarm when the system detects an obstruction or the depth is
less than the entered value.
The ability to effectively avoid running aground with Garmin FrontVü sonar decreases as your speed rises above
8 knots.
LiveVü and Garmin FrontVü Appearance Settings
From a LiveVü or Garmin FrontVü Panoptix sonar view, select Menu > Sonar Setup > Appearance.
Color Scheme: Sets the color palette.
Color Gain: Adjusts the intensity of colors shown on the screen.
You can select a higher color gain value to see targets higher in the water column. A higher color gain value
also allow you to differentiate low intensity returns higher in the water column, but this causes a loss in the
differentiation of the returns at the bottom. You can select a lower color gain value when targets are near the
bottom, to help you distinguish between targets and high intensity returns such as sand, rock, and mud.
Trails: Sets the how long the trails appear on the screen. The trails show the movement of the target.
Bottom Fill: Colors the bottom brown to distinguish it from the water returns.
Grid Overlay: Shows a grid of range lines.
Scroll History: Shows the sonar history in a traditional sonar view.
RealVü Appearance Settings
From a RealVü sonar view, select Menu > Sonar Setup > Appearance.
Point Colors: Sets a different color palette for the sonar return points.
Bottom Colors: Sets the color scheme for the bottom.
Bottom Style: Sets the style for the bottom. When you are in deep water, you can select the Points option and
manually set the range to a shallower value.
Color Key: Shows a legend of the depths the colors represent.
