Heading Line and Angle MarkersThe heading line is an extension drawn on the map from thebow of the boat in the direction of travel. Angle markers indicaterelative position from the heading or course over ground, whichare helpful for casting or finding reference points.Setting the Heading Line and Angle MarkersThe heading line is an extension drawn on the map from thebow of the boat in the direction of travel. Angle markers indicaterelative position from the heading or course over ground, whichare helpful for casting or finding reference points.You can show the heading line and the course over ground(COG) line on the chart.COG is your direction of movement. Heading is the direction thebow of the boat is pointed, when a heading sensor is connected.1 From a chart, select Menu > Layers > My Vessel > HeadingLine.2 Angle Markers3 If necessary, select Source, and select an option:• To automatically use the available source, select Auto.• To use the GPS antenna heading for COG, select GPSHeading (COG).• To use data from a connected heading sensor, selectNorth Reference.• To use data from both a connected heading sensor andthe GPS antenna, select COG and Heading.This displays both the heading line and the COG line onthe chart.4 Select Display, and select an option:• Select Distance > Distance, and enter the length of theline shown on the chart.• Select Time > Time, and enter the time used to calculatethe distance your boat will travel in the specified time atyour present speed.Sonar FishfinderWhen properly connected to a compatible transducer, yourchartplotter can be used as a fishfinder.For more information about which transducer is best for yourneeds, go to www.garmin.com/transducers.Different sonar views can help you view the fish in the area. Thesonar views available vary depending on the type of transducerand sounder module connected to the chartplotter. For example,you can view certain Panoptix™ sonar screens only if you have acompatible Panoptix transducer connected.There are four basic styles of sonar views available: a full-screen view, a split-screen view that combines two or moreviews, a split-zoom view, and a split-frequency view thatdisplays two different frequencies. You can customize thesettings for each view in the screen. For example, if you areviewing the split-frequency view, you can separately adjust thegain for each frequency.If you do not see an arrangement of sonar views to suit yourneeds, you can create a custom combination screen (Creating aNew Combination Page, page 3) or a SmartMode layout (Addinga SmartMode Layout, page 2).Stopping the Transmission of Sonar SignalsFrom a sonar screen, select Menu > Transmit.Changing the Sonar View1 From a combination screen or SmartMode layout with sonar,select the window to change.2 Select Menu > Change Sonar.3 Select a sonar view.Traditional Sonar ViewThere are several full-screen views available, depending on theequipment connected.The full-screen Traditional sonar view show a large image of thesonar readings from a transducer.

For information about compatible transducers, go towww.garmin.com/transducers.Garmin ClearVü high-frequency sonar provides a detailedpicture of the fishing environment around the boat in a detailedrepresentation of structures the boat is passing over.Traditional transducers emit a conical beam. The GarminClearVü scanning sonar technology emits two narrow beams,similar to the shape of the beam in a copying machine. Thesebeams provide a clearer, picture-like image of what is beneaththe boat.SideVü Sonar ViewNOTE: Not all models provide built-in SideVü sonar support. Ifyour model does not provide built-in SideVü sonar, you need acompatible sounder module and compatible SideVü transducer.Sonar Fishfinder 21
