2 Select an option:• To adjust the scroll speed automatically using speed-over-ground, select Auto.The Auto setting selects a scroll rate to match the boatspeed, so targets in the water are drawn with the correctaspect ratio and appear less distorted. When viewingGarmin ClearVü or SideVü sonar views, it is recommendto use the Auto setting.• To use a very fast scroll speed, select Ultrascroll®.The Ultrascroll option quickly scrolls new sonar data, butwith a reduced image quality. For most situations, the Fastoption provides a good balance between a quicklyscrolling image and targets that are less distorted.Setting the Bottom Search LimitYou can set a maximum depth at which the auto range featuresearches for the bottom. A lower limit acquires data about thebottom faster than a higher limit.1 From a sonar screen, select > Sonar Setup > BottomSearch Limit.2 Select a range.Sonar Appearance SettingsFrom a sonar view, select > Sonar Setup > Appearance.Color Scheme: Sets the color scheme.Edge: Highlights the strongest signal from the bottom to helpdefine the hardness or softness of the signal.A-Scope: Displays a vertical flasher along the right side of thescreen that shows instantaneously the range to targets alonga scale.Fish Symbols: Sets how the sonar interprets suspendedtargets.Turning on the A-ScopeThe a-scope is a vertical flasher along the right side of the full-screen sonar view. This feature expands the most recentlyreceived sonar data so that it is easier to see. It can also behelpful for detecting fish that are close to the bottom.NOTE: This feature is not available on all sonar screens.From the full screen page, select > Sonar Setup >Appearance > A-Scope.À A-ScopeÁ Diameter of the sonar cone at the present depthConfiguring the Appearance of Suspended TargetsNOTE: Configuring the appearance of suspended targets onone screen applies that setting to all screens.NOTE: This feature is not available on all sonar views.Shows suspended targets as symbols.Shows suspended targets as symbols with target depthinformation.Shows suspended targets as symbols with background sonarinformation.Shows suspended targets as symbols with background sonarinformation and target depth information.1 From a sonar screen, select > Sonar Setup >Appearance > Fish Symbols.2 Select an option.Sonar Noise Rejection SettingsFrom a sonar view, select > Sonar Setup > Noise Reject.Interference: Adjusts the sensitivity to reduce the effects ofinterference from nearby sources of noise.When you adjust the interference setting from off À throughlow Á, medium Â, and high Ã, noise is gradually removed,but there is little effect on the strong target returns. Youshould use the lowest interference setting that achieves thedesired improvement to remove interference from the screen.Correcting installation issues that cause noise is the best wayto eliminate interference.Surface Noise: Hides sonar returns near the surface of thewater. Hiding surface noise helps reduce screen clutter.Surface noise À is caused by interference between thetransducer and water. You can hide surface noise Á to helpreduce clutter. Wider beam widths (lower frequencies) canshow more targets, but can generate more surface noise.TVG: Reduces surface noise.This control is best used for situations when you want tocontrol and suppress clutter or noise near the water surface.It also allows for the display of targets near the surface thatare otherwise hidden or masked by surface noise.Overlay Number SettingsYou can customize the data shown on the sonar screen.From a sonar screen, select > Overlay Numbers.Navigation Inset: Shows the navigation inset when the vesselis navigating to a destination.Compass Tape: Shows the compass tape data bar.Device Voltage: Shows the voltage of the device.Depth: Shows the transducer's current depth.Speed: Shows the vessel's current speed.Water Temp.: Shows the current water temperature.Time of Day: Shows the current time of day.6 Sonar Fishfinder
