[. . . ] At the same time, a cursor dialog box is displayed at the top of the screen with the distance and bearing from the boat to the cursor position and the latitude/longitude coordinates of the cursor. When the cursor is active on the display, you can also use the 4-WAY Cursor Control key to move the cursor diagonally. Chart View with Cursor Present Viewing Cartography 74 Zooming: Press the Plus (+) key to Zoom In and the Minus (-) key to Zoom Out to see the cartography at different magnification levels. If you zoom in beyond the available chart data, the display will go into Overzoom mode whereby the last available chart data is amplified to reflect the level selected. If you zoom in so far that no cartography is available, a lat/long grid will be drawn instead. Screen Snapshots and Recording Icons: When a waypoint is created while Screen Snapshot and Recording is active, the waypoint will appear as a snapshot icon or recording icon in chart views. Chart Info: Press the INFO key to get detailed information about the chart. If the cursor is active, you will see information about the chart objects located near the cursor. Use the 4-WAY Cursor Control key to select the Nearest Port, the Nearest Tide Station, or the Nearest Current Station and see information about any of these objects. NOTE: The built-in UniMapTM does not contain any Port, Tide, or Current information. This information is only available from optionalpurchase MMC/SD cards. Nearest Port: The position and services information for the nearest port to your present position will be displayed. Press the EXIT key to remove the information box and the cursor bull's eye will be centered over the port position. The cursor information boxes will indicate the distance and bearing to the port from your present position. Nearest Tide Station: Tide information for the nearest tide station to your present position will be displayed. This includes the position of the station and the times of the high and low tides for today's date. A tide graph is also displayed showing the rise and fall of the tides for the 24 hour time period encompassing the date. You can change the date to look at tide information before or after the date displayed by pressing the LEFT or RIGHT Cursor key respectively. Press the EXIT key to remove the information box, and the cursor bull's eye will be centered over the tide station position. The cursor information boxes indicate the distance and bearing to the tide station from your present position. Nearest Current Station: Current information for the nearest current station to your present position will be displayed. This includes the position of the station and the current changes for today. Two graphs are also presented that show the time, direction, and flow speed of the current changes for the 24 hour time period of today's date. You can change the date to look at current information before or after the date displayed by pressing the LEFT or RIGHT Cursor key respectively. Press the EXIT key to remove the information box, and the cursor bull's eye will be centered over the current station position. [. . . ] Speed Over Ground (SOG) The measurement of the boat's progress across a given distance and the speed measurement provided by GPS. An alternate, Speed Through Water, is provided by a speed paddlewheel, and is the measurement of the flow past the boat, which may vary depending on current speed and direction. Speed Over Ground is optimal for navigation because accurate destination times can be derived from this measurement. Humminbird® products allow for input and display of both speed measurements. GPS & Navigation Terms Trackplotter A navigation device that shows Present Position, along with Track, Waypoint, and Routes, but NO MAP in the background. [. . . ]
