You will be able to get a result that is accurate enough Cabal online alz to land you in the grid
There are two practical implementations of using multiple probes. One is to spread out stronger-range probes to catch people who warp Cabal online alz around in an attempt to avoid you.
Note that if you use multiple probes and the target is not in the intersection of these probes, both your signal strength and accuracy will be lower than if you just used one probe.
The other usage of multiple probes is to catch someone who is using the scanner to see when you drop them.
By placing two or three Spook (20 AU) probes just outside the range of the Directional Scanner so that they intersect above the target, you will be able to get a result that is accurate enough to land you in the same grid as the target without him ever seeing you on his scanner.
This may not be easy, depending a lot on the system's layout and where the target is hiding. You will have to use the system map to see for yourself.
Another way to make it less likely that your probes will be picked up on the scanner is to destroy them as soon as you get the result you want.
Destruction of a probe can even be done while cloaked and in warp. Done right, and with good skills, your probes should not show up in space for more than 40 seconds at most.
