transducer. The attitude and heading reference

system (AHRS) must be calibrated use this feature

World Map: Uses either a basic world map or a shaded relief

map on the chart. These differences are visible only when

zoomed out too far to see the detailed charts.

Spot Depths: Turns on spot soundings and sets a dangerous

depth. Spot depths that are equal to or more shallow than the

dangerous depth are indicated by red text.

Shallow Shading: Sets the shades from the shoreline to the

specified depth.

Depth Shading: Specifies an upper and lower depth to shade

between.

Symbols: Shows and configures the appearance of various

symbols on the chart, such as the vessel icon, navaid

Hazard Colors: Shows shallow water and land with a color

scale. Blue indicates deep water, yellow is shallow water, and

red is very shallow water.

Preferred Depth: Sets the appearance of a safe depth for the

Mariner’s Eye 3D chart view.

Laylines Settings

To use the laylines features, you must connect a wind sensor to

the chartplotter.

When in sailing mode (Setting the Vessel Type,

page

can display laylines on the navigation chart. Laylines can be

very helpful when racing.

From the navigation chart, select Menu >

Sailing > Laylines

Display: Sets how the laylines and vessel appear on the chart,

and sets the length of the laylines.

Sailing Ang.: Allows you to select how the device calculates

laylines. The Actual

option calculates the laylines using the

measured wind angle from the wind sensor. The Manual

option calculates the laylines using manually entered

windward and leeward angles.

Windward Ang.: Allows you to set a layline based on the

windward sailing angle.

Leeward Ang.: Allows you to set a layline based on the leeward

sailing angle.

Tide Correction: Corrects the laylines based on the tide.

Layline Filter: Filters the layline data based on the time interval

entered. For a smoother layline that filters out some of the

changes in the boat's heading or true wind angle, enter a

higher number. For laylines that display a higher sensitivity to

changes in the boat's heading or true wind angle, enter a

lower number.

Contours

Mapping

WARNING

The

Garmin Quickdraw Contours mapping feature allows users

to generate maps. Garmin makes no representations about the

accuracy, reliability, completeness or timeliness of the maps

generated by third parties. Any use or reliance on the maps

generated by third parties is at your own risk.

The

Garmin Quickdraw Contours mapping feature allows you to

instantly create maps with contours and depth labels for any

body of water.

When Garmin Quickdraw Contours records data, a colored

circle surrounds the vessel icon. This circle represents the

approximate area of the map that is scanned by each pass.

A green circle indicates good depth and GPS position, and a

speed under 16 km/h (10 mph). A yellow circle indicates good

depth and GPS position, and a speed between 16 and 32 km/h

(10 and 20 mph). A red circle indicates poor depth or GPS

position, and a speed above 32 km/h (20 mph).

You can view Garmin Quickdraw Contours in a combination

screen or as a single view on the map.

The amount of saved data depends on the size of your memory

card, your sonar source, and the speed of your boat as you

record data. You can record longer when you use a single-beam

sonar. It is estimated that you might be able to record about

1,500 hours of data onto a 2 GB memory card.

When you record data on a memory card in your chartplotter,

the new data is added to your existing Garmin Quickdraw

Contours map, and is saved on the memory card. When you

insert a new memory card, the existing data does not transfer

onto the new card.
