Configuring the Heading Source of the Wind Gauge

From the wind gauge, select Menu > Compass Gauge > 
Heading Source.

Select GPS Hdg or Magnetic.
NOTE: When moving at low speeds or when stationary, the 
magnetic compass source is more accurate than the GPS 
source.
Customizing the Close-Hauled Wind Gauge
You can specify the range of the close-hauled wind gauge for 
both the upwind scale and the downwind scale.
1
From the wind gauge, select Menu > Compass Gauge > 
Set Gauge Type > Close Hauled Gauge.

Select an option:
• To set the maximum and minimum values that appear 
when the upwind close-hauled wind gauge appears, 
select Change Upwind Scale, and set the angles.

when the downwind close-hauled wind gauge appears, 
select Change Downwind Scale, and set the angles.
• To view true or apparent wind, select Wind, and select an 
option.
Viewing Graphs
Before you can view graphs of various environmental changes, 
such as temperature, depth, and wind, you must have an 
appropriate transducer or sensor connected to the network.
Select Info > Trip & Graphs > Graphs.
Setting the Graph Range and Time Scales
You can indicate the amount of time and the range of depth that 
appear in the depth and water temperature graphs.
1
From a graph, select Graph Setup.
2
Select an option:
• To set a time-elapsed scale, select Duration. The default 
setting is 10 minutes. Increasing the time-elapsed scale 
allows you to view variations over a longer period of time. 
Decreasing the time-elapsed scale allows you to view 
more detail over a shorter period of time.
• To set the graph scale, select Scale. Increasing the scale 
allows you to view more variation in readings. Decreasing 
the scale allows you to view more detail in the variation.
