To make it easier for new players to learn how to probe, I've decided to create this little picture guide on how to set up a series of probes to scan down targets.
Four Probe Setup
1. Deploy two probes. File:P4-1.jpg
2. CTRL+SHIFT+Drag them downward. File:P4-2.jpg
3. Deploy two probes. File:P4-3.jpg
4. Drag the first two outward to form a triangle File:P4-4.jpg
5. Drag the third probe to center of the triangle. File:P4-5.jpg
6. Drag the center probe vertically. File:P4-6.png
7. Expand the resolution to fit.
8. Drag the probes in/out, and expand/contract the resolution as needed, CTRL+SHIFT to move the entire group at once. File:P4-7.png
