Walk in the direction that the telescope is pointing, and use Survey again. Repeat doing this until a lootable item appears. The telescope points roughly to the artifact, the closer you are, the more accurate the direction. Beside it is a rod with a light on the mmat. A red light reading also has the worst accuracy - it is usually best to take several readings to determine the direction. When the green light begins blinking, you mat previous years question papers usually within just a few steps of the artifact.
