Depth: Adjusts the items on the depth layer (Water Layer Settings, page 9). Restricted Areas: Shows information about restricted areas on the chart. Photo Points: Shows camera icons for aerial photos (Viewing Aerial Photos of Landmarks, page 6). My Vessel Layer Settings From a chart, select MENU > Layers > My Vessel. Heading Line: Shows and adjusts the heading line, which is a line drawn on the map from the bow of the boat in the direction of travel (Setting the Heading Line and Angle Markers, page 5). Laylines: Adjusts the laylines, when in sailing mode (Laylines Settings, page 9). Roses: Allows you to display roses on the chart. Wind roses show a visual representation of the wind angle or direction provided by the connected wind sensor. The compass rose indicates the compass direction oriented to the heading of the boat. Vessel Icon: Sets the icon that represents your present location on the chart. Laylines Settings To use the laylines features, you must connect a wind sensor to the chartplotter. When in sailing mode (Setting the Vessel Type, page 2), you can display laylines on the navigation chart. Laylines can be very helpful when racing. From the navigation chart, select MENU > Layers > My Vessel > Laylines > Setup. Display: Sets how the laylines and vessel appear on the chart, and sets the length of the laylines. Sailing Angle: Allows you to select how the device calculates laylines. The Actual option calculates the laylines using the measured wind angle from the wind sensor. The Manual option calculates the laylines using manually entered windward and leeward angles. Windward Angle: Allows you to set a layline based on the windward sailing angle. Leeward Angle: Allows you to set a layline based on the leeward sailing angle. Tide Correction: Corrects the laylines based on the tide. Filter Time Constant: Filters the layline data based on the time interval entered. For a smoother layline that filters out some of the changes in the boat's heading or true wind angle, enter a higher number. For laylines that display a higher sensitivity to changes in the boat's heading or true wind angle, enter a lower number. User Data Layer Settings You can show user data, such as waypoints, boundaries, and tracks, on the charts. From a chart, select MENU > Layers > User Data. Waypoints: Shows waypoints on the chart and opens the list of waypoints. Boundaries: Shows boundaries on the chart and opens the list of boundaries. Tracks: Shows tracks on the chart. Other Vessels Layer Settings NOTE: These options require connected accessories, such as an AIS receiver, radar, or VHF radio. From a chart, select MENU > Layers > Other Vessels. DSC: Sets how DSC vessels and trails appear on the chart, and shows the DSC list. AIS: Sets how AIS vessels and trails appear on the chart, and shows the AIS list. Details: Shows other vessel details on the chart. Projected Heading: Sets the projected heading time for AIS- activated and MARPA-tagged vessels. AIS Alarm: Sets the safe-zone collision alarm (Setting the Safe- Zone Collision Alarm, page 7). Water Layer Settings From a chart, select MENU > Layers > Water. NOTE: The menu may contain some settings that are not supported by your installed charts or your present location. If you make changes to those settings, the changes will not impact the chart view. Depth Shading: Specifies an upper and lower depth to shade between. Shallow Shading: Sets the shades from the shoreline to the specified depth. Spot Depths: Turns on spot soundings and sets a dangerous depth. Spot depths that are equal to or more shallow than the dangerous depth are indicated by red text. Fishing Contours: Sets the zoom level for a detailed view of bottom contours and depth soundings and simplifies map presentation for optimal use while fishing. Relief Shading: Shows the gradient of the bottom with shading. This feature is available only with some premium maps. Sonar Imagery: Shows sonar imagery to help show the density of the bottom. This feature is available only with some premium maps. Lake Level: Sets the present water level of the lake. This feature is available only with some premium maps. Depth Range Shading You can set color ranges on your map to show the water depths where your target fish are currently biting. You can set deeper ranges to monitor how quickly the bottom depth changes within a specific depth range. You can create up to ten depth ranges. For inland fishing, a maximum of five depth ranges can help reduce map clutter. The depth ranges apply to all charts and all bodies of water. Some Garmin LakeVü™ and premium supplemental charts have multiple depth range shading by default. Charts and 3D Chart Views 9
