Different sonar views can help you view thefish in the area.The adjustments you can make to each sonar view varydepending on the view you are in and the chartplotter model,sounder module, and transducer 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 adjust the gain foreach of the frequencies separately.If you do not see an arrangement of sonar views to suit yourneeds, you can create a custom screen (Adding a CustomCombination Screen).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. The range scale along theright side of the screen shows the depth of detected objects asthe 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.14 Sonar
