Trackline Extension
Trackline Extension is a new tracking option that provides a visual
interpretation of your velocity. It charts how long it will take to travel a
predetermined distance based on your current navigational
information. Distance is shown on one side of the track with estimated
time of arrival on the other. Below the Trackline Extension window are
two check boxes — Show Time and Show Distance — which allow you
to turn on or off the time and/or distance settings.

Map Overlays (Range Rings; Lat/Long Grid)
The map screen can be customized with four range rings and/or grids
that divide the plotter into equal segments of latitude and longitude.
Range rings are handy for visually estimating distances on the map.
The ring diameters are based on the current zoom range. For example:
at the 100-mile zoom, the screen will show two rings with your current
position in the center. The large ring touching the left and right sides of
the screen is 100 miles in diameter (same as the zoom range). The
second smaller ring is 50 miles in diameter (always 1/2 the zoom
range). The distance from your current position to the smaller ring (the
ring's radius) is 25 miles (always 1/4 the zoom range). With the arrow
