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 with the ECHOMAP Plus 70/90,page 3).Stopping the Transmission of Sonar Signals• To disable the active sonar, from the sonar screen, selectMENU > Sonar Transmit.• To disable all sonar transmissions, press , and selectDisable Sonar.Changing the Sonar View1 From a combination screen with sonar, select MENU >Configure Combination > Edit Combination.2 Select the window to change.3 Select a sonar view.Traditional Sonar ViewThere are several full-screen views available, depending on thetransducer that is connected.The full-screen Traditional sonar view shows a large image ofthe sonar readings from a transducer. The range scale along theright side of the screen shows the depth of detected objects asthe screen scrolls from the right to the left.Depth informationSuspended targets or fishBottom of the body of waterSplit-Frequency Sonar ViewIn the split-frequency sonar view, the two sides of the screenshow a full-view graph of sonar data of different frequencies.NOTE: The split-frequency sonar view requires the use of adual-frequency transducer.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.Garmin ClearVü Sonar ViewNOTE: To receive Garmin ClearVü scanning sonar, you need acompatible chartplotter or fishfinder and a compatibletransducer. For information about compatible transducers, go togarmin.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.If your model does provide built-in SideVü sonar, you need acompatible SideVü transducer.SideVü scanning sonar technology shows you a picture of whatlies to the sides of the boat.
