The adjustments you can make to each sonar view varydepending on the view you are in and the chartplotter model andtransducer you have connected.Sonar ViewsThe sonar views available vary depending on the type oftransducer and optional sounder module connected to thechartplotter. For example, you can view the Split Frequencyview only if you have a dual-frequency 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.Full-Screen Sonar ViewThere are several full-screen views available, depending on theequipment connected. The full-screen sonar views show a largeimage of the sonar readings from a transducer. The range scalealong the right side of the screen shows the depth of detectedobjects as the screen scrolls from the right to the left.À Depth informationÁ Suspended targets or fishÂ Bottom of the body of waterDownVü Sonar ViewNOTE: Not all models support DownVü sonar technology andtransducers.NOTE: To receive DownVü scanning sonar, you need acompatible chartplotter or fishfinder and a compatibletransducer.DownVü high-frequency sonar provides a clearer picture belowthe boat, providing a more detailed representation of structuresthe boat is passing over.Traditional transducers emit a conical beam. The DownVüscanning sonar technology emits a narrow beam, similar to theshape of the beam in a copying machine. This beam provides aclearer, picture-like image of what is beneath the boat.SideVü Sonar ViewNOTE: Not all models support SideVü sonar and scanningtransducers.NOTE: To receive SideVü scanning sonar, you need acompatible chartplotter and a compatible transducer.SideVü scanning sonar technology shows you a picture of whatlies to the sides of the boat. You can use this as a search tool tofind structures and fish.À Left side of the boatÁ Right side of the boatÂ The transducer on your vesselÃ TreesÄ Old tiresÅ LogsÆ Distance from the side of the boatSideVü/DownVü Scanning TechnologyInstead of a more common conical beam, the SideVü/DownVütransducer uses a flat beam to scan the water and ground to thesides of your boat.Split-Screen Sonar ViewsThe split-screen sonar views enable you to view differentcombinations of sonar data simultaneously. For example, youcan view traditional sonar and DownVü sonar views in onescreen. You can edit the layout of a split-screen sonar view toresize the window and rearrange the data.The scroll rates of the traditional and DownVü sonar views aresynchronized to make the split-screen views easier to read.Split-Zoom Sonar ViewThe split-zoom sonar view shows a full-view graph of sonarreadings, and a magnified portion of that graph, on the samescreen.Split-Frequency Sonar ViewIn the split-frequency sonar view, one side of the screen showsa full-view graph of high frequency sonar data, and the otherside of the screen shows a full-view graph of lower frequencysonar data.NOTE: The split-frequency sonar view requires the use of adual-frequency transducer.Selecting the Transducer TypeBefore you can select the transducer type, you must know whatkind of transducer you have.If you are connecting a transducer that was not included with thechartplotter, you may need to set the transducer type to makethe sonar function properly. If the device automatically detectedyour transducer, this option does not appear.Sonar 13
