Heading Line and Angle Markers The heading line is an extension drawn on the map from the bow of the boat in the direction of travel. Angle markers indicate relative position from the heading or course over ground, which are helpful for casting or finding reference points. Setting the Heading Line and Angle Markers The heading line is an extension drawn on the map from the bow of the boat in the direction of travel. Angle markers indicate relative position from the heading or course over ground, which are 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 the bow of the boat is pointed, when a heading sensor is connected. 1 From a chart, select Menu > Layers > My Vessel > Heading Line > Angle Markers. 2 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 GPS Heading (COG). • To use data from a connected heading sensor, select North Reference. • To use data from both a connected heading sensor and the GPS antenna, select COG and Heading. This displays both the heading line and the COG line on the chart. 3 Select Display, and select an option: • Select Distance > Distance, and enter the length of the line shown on the chart. • Select Time > Time, and enter the time used to calculate the distance your boat will travel in the specified time at your present speed. Sonar Fishfinder When properly connected to a transducer, your compatible chartplotter can be used as a fishfinder. Chartplotter models without an xsv or xs in their names require a Garmin sounder module and transducer to display sonar information. For more information about which transducer is best for your needs, go to garmin.com/transducers. Different sonar views can help you view the fish in the area. The sonar views available vary depending on the type of transducer and sounder module connected to the chartplotter. For example, you can view certain Panoptix™ sonar screens only if you have a compatible Panoptix transducer connected. There are four basic styles of sonar views available: a fullscreen view, a split-screen view that combines two or more views, a split-zoom view, and a split-frequency view that displays two different frequencies. You can customize the settings for each view in the screen. For example, if you are viewing the split-frequency view, you can separately adjust the gain for each frequency. If you do not see an arrangement of sonar views to suit your needs, you can create a custom combination screen (Creating a New Combination Page, page 5) or a SmartMode layout (Adding a SmartMode Layout, page 4). Stopping the Transmission of Sonar Signals • To disable the active sonar, from the sonar screen, select Menu > Transmit. • To disable all sonar transmissions, press , and select Disable All Sonar Trans.. Changing the Sonar View 1 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 View There are several full-screen views available, depending on the transducer that is connected. The full-screen Traditional sonar view shows a large image of the sonar readings from a transducer. The range scale along the right side of the screen shows the depth of detected objects as the screen scrolls from the right to the left. Depth information Suspended targets or fish Bottom of the body of water Split-Frequency Sonar View In the split-frequency sonar view, the two sides of the screen show a full-view graph of sonar data of different frequencies. NOTE: The split-frequency sonar view requires the use of a dual-frequency transducer. Split-Zoom Sonar View The split-zoom sonar view shows a full-view graph of sonar readings, and a magnified portion of that graph, on the same screen. Garmin ClearVü Sonar View NOTE: To receive Garmin ClearVü scanning sonar, you need a compatible chartplotter or fishfinder and a compatible transducer. For information about compatible transducers, go to garmin.com/transducers. Garmin ClearVü high-frequency sonar provides a detailed picture of the fishing environment around the boat in a detailed representation of structures the boat is passing over. Sonar Fishfinder 25
