“Two Position Formats” is similar to “Digital Data”, except it adds two present position boxes, one showing latitude/longitude and the other shows the present po- sition in UTM.
“Two Maps” shows two maps side-by-side. You can customized each map with different settings. For example, the map on the left can have a zoom range of .5 miles, while the one on the right has a range of 10 miles. This lets you zoom-in on one side, while seeing a much larger area on the other. Press the PAGES key, then an arrow key to select the right or left map.
“Map With Sonar” shows the map on the left side of the screen and the sonar on the right.
The Z-IN and Z-OUT keys zoom- in and out all maps to enlarge or reduce their coverage area. The available ranges are: 0.1, 0.15, 0.2, 0.3, 0.4, 0.6, 0.8, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100, 150, 200, 300, 400, 600,
800, 1000, 1500, 2000, 3000, and 4000 miles.
Cursor
Pressing an arrow key turns on two dotted lines that intersect at the present position symbol. These lines are called a “cursor” and have a variety of uses.
