We need to find roughly where they are in the system using the directional scanner
The Directional Scanner has two relevant options; you can limit it to show only the things you have set your overview to show Maple Story Mesos, or you can have it show everything it can find.
With the Revelations patch, the list of things the scanner will pick up has been limited to only include things related to finding and avoiding other players.
Narrowing the Search: In order to narrow down the search for our target, we need to find roughly where they are in the system using the directional scanner, adjusting the range and angle.
The range is defined in kilometers, the maximum being 2,147,483,647 km (approximately 14.35 AU). If you input a value higher than this it will automatically reset to this value. If the target is more than 14.35 AU away, you will not be able to see them on your scanner.
Angle is defined in degrees; 360 mean all around in every direction, while 90 is roughly the same as your viewing angle.
The direction of the scan is centered on where your camera is pointing; you can see both the direction of the camera and the span of your scan by clicking F11 and looking at the top-down solar system view.
