Understanding Breadcrumbs

Breadcrumbs (often called "Track Log" or "Track Plot") are a series of automatic, temporary position marks recorded at set intervals or distances as your vessel moves. They create a visual trail on the chartplotter screen, showing exactly where you have been.

Feature	Description
Automatic Recording	Continuously logs position when enabled and moving.
Visual Trail	Appears as a dotted or solid line on the map display.
Retrace Path	Allows you to navigate back along your recorded track.
Temporary Storage	Usually stored in active memory until cleared or the unit is powered off (unless saved).

Enabling/Disabling Breadcrumbs

To start recording your track:

From the Home screen, press MENU.
Select Navigation > Tracks.
Ensure Record Track is set to On.
To disable, set Record Track to Off.

NOTE: The track will automatically record when enabled and your boat's speed is above the set threshold.

Customizing Breadcrumb Settings

Adjust how and when breadcrumbs are recorded for optimal use.

Go to MENU > Navigation > Tracks > Track Log Setup.
Record Method: Choose Auto (records based on time/distance change), Distance (marks at set intervals), or Time (marks at time intervals).
Interval: Set the distance (e.g., 0.02 nm) or time (e.g., 10 sec) between marks.
Color & Width: Customize the appearance of the track line on the chart.
Record When Stopped: Choose whether to log points when speed is below threshold.

TIP: For detailed backtracking in complex areas, use a shorter interval (e.g., 0.01 nm). For open water, a longer interval saves memory.

Viewing and Following a Trail

To View: The active breadcrumb trail appears automatically on the Chart page when recording is on. Ensure the track overlay is enabled in Chart settings.
To Follow Back:
1. With a recorded track active, press MENU.
2. Select Navigation > Tracks.
3. Select the active track (e.g., "Current Track").
4. Select Follow Track and choose direction (Forward/Reverse).
5. The unit will provide navigation guidance along the exact path recorded.

Clearing Breadcrumbs

To erase the current breadcrumb trail from the display and memory:

Go to MENU > Navigation > Tracks.
Select Current Track.
Select Clear Track and confirm.

WARNING! Clearing is permanent unless the track has been previously saved. Ensure you save any important track data first.

Saving a Track from Breadcrumbs

To permanently save a breadcrumb trail for future use:

Navigate to MENU > Navigation > Tracks > Current Track.
Select Save Track.
Enter a descriptive name (e.g., "Inlet Approach 10-15").
Press OK to save. The track is now stored in the Saved Tracks list and can be activated for navigation at any time.

Breadcrumbs vs. Waypoints

Understand the difference to use each feature effectively.

Breadcrumbs (Track Log)	Waypoints
Automatic, continuous recording.	Manually created single points.
Creates a line showing path traveled.	Marks specific spots (e.g., buoy, dock).
Best for retracing an exact route.	Best for marking destinations or hazards.
Temporary until saved.	Permanently saved until deleted.

Tips for Effective Use

Start Early: Enable breadcrumbs at the beginning of your trip to capture the entire journey.
Memory Management: The unit has limited active track memory. Save long or important tracks regularly and clear old ones.
Low-Speed Detail: In marinas or fishing spots, reduce the interval setting to capture more detailed maneuvers.
Safety: Use the "Follow Track" feature in low visibility to safely retrace your entry path.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No breadcrumb trail showing	Recording disabled; Chart overlay off	Enable 'Record Track' in Tracks menu. Check Chart settings to show tracks.
Track line is jagged or inaccurate	Poor GPS signal; Interval too long	Ensure clear view of sky. Shorten the recording interval in setup.
Cannot save track	No active track data; Memory full	Record a track first. Delete old saved tracks or waypoints to free space.
'Follow Track' not working	Track too short; Function misselected	Ensure track has sufficient length. Select 'Follow Track' from the Saved Tracks menu, not Current Track.
Breadcrumbs disappear on power off	Track not saved	Active track log is volatile. Save the track before powering down if you need it later.
