• LINE: This tool draws a straight path between two points to help you plan where the ship should go.

Range Selection and Mode of Operation

Display Orientations

• North Up: The map stays still with North always at the top, which is best for comparing your screen to a paper chart.

• Course Up: The top of the screen shows the direction you intended to travel, making it best for staying on a planned path.

• Head Up: The top of the screen shows exactly where the front of your boat is pointing right now, which is best for seeing things directly ahead of you.

Motion and Vectors

• True Motion: Fixed objects like land stay still while your boat moves across the screen, making it best for seeing your actual travel path.

• True Vector: A line shows the real speed and direction of other ships, which is best for knowing exactly where those ships are heading.

• Relative Motion: Your boat stays in the center of the screen while everything else moves around you, making it best for spotting things that might hit you.

• Relative Vector: A line shows if another ship is getting closer or moving away from your boat, which is best for avoiding crashes at sea.

ARPA functions

• Cease Track: This button stops the radar from following a specific target, and it is best used when a ship has passed safely and you no longer need to watch it.

• Test: This runs a quick check to make sure the computer's tracking system is working correctly, and it is best used before you start your watch or enter busy waters.

• Auto Acquire: The radar automatically finds and starts tracking any new ships that enter a certain area, which is best used when you are in the open ocean and want the computer to stay alert for you.

• History: This shows dots or lines where a ship has been in the past few minutes, and it is best used to see if another ship is turning or changing its speed.
