2Select an option:

•To calculate the vessel speed based on data from the water-speed sensor, select Water Speed.

•To calculate the vessel speed based on GPS data, select GPS Speed.

Configuring the Heading Source of the Wind Gauge

You can specify the source of the heading displayed on the wind gauge. Magnetic heading is the heading data received from a heading sensor, and GPS heading is calculated by your chartplotter GPS (course over ground).

1From the wind gauge, select Menu > Compass Gauge > Heading Source.

2Select 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.

1From the wind gauge, select Menu > Compass Gauge > Set Gauge Type > Close Hauled Gauge.

2Select 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.

•To set the maximum and minimum values that appear 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.

1From 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.
