• To continuously record a track log, replacing the oldest track data with new data, select Wrap.

Configuring the Recording Interval of the Track Log

You can indicate the frequency at which the track plot is recorded. Recording more frequent plots is more
accurate but fills the track log faster. The resolution interval is recommended for the most efficient use of
memory.
1 Select Info > User Data > Tracks > Active Track Options > Interval.
2 Select an option:
• To record the track based on a distance between points, select Interval > Distance > Change, and enter
the distance.
• To record the track based on a time interval, select Interval > Time > Change, and enter the time interval.
• To record the track plot based on a variance from your course, select Interval > Resolution > Change,
and enter the maximum error allowed from the true course before recording a track point. This is the
recommended recording option.

Boundaries

Boundaries allow you to avoid or remain in designated areas in a body of water. You can set an alarm to alert
you when you enter or exit a boundary.
You can create boundary areas, lines, and circles using the map. You can also convert saved tracks and routes
into boundary lines. You can create a boundary area using waypoints by creating a route from the waypoints,
and converting the route into a boundary line.
You can select a boundary to act as the active boundary. You can add the active boundary data to the data
fields on the chart.

Creating a Boundary

1 Select Info > User Data > Boundaries > New.
2 Select a boundary shape.
3 Follow the on-screen instructions.
