option calculates the laylines using manually entered
windward and leeward angles.
Windward Angle : Allows you to set a layline based on the
windward sailing angle.
Leeward Angle : Allows you to set a layline based on the
leeward sailing angle.
Tide Correction : Corrects the laylines based on the tide.
Filter Time Constant : 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.

Depth Range Shading
You can set color ranges on your map to show the water depths
where your target fish are currently biting. You can set deeper
ranges to monitor how quickly the bottom depth changes within
a specific depth range. You can create up to ten depth ranges.
For inland fishing, a maximum of five depth ranges can help
reduce map clutter. The depth ranges apply to all charts and all
bodies of water.
Some Garmin LakeVü
™

multiple depth range shading by default.
