Recommended Requirements

The recommended skills below all help shaving time required to probe a shipThis is important because ships can move at any time while you probe it, so the faster you obtain the signal the less chances the target will get awayIt is not necessary to train all those skills to level V, considering some of these skills have high training time multiplier

Astrometrics IV: At level I you control 4 probes, at level IV you can control 6 probesWith more probes it's faster to get a 100% signal strength

Astrometric Pinpointing IV: Reduces scan deviation by 10% per levelScan probes will estimate better the position of the signaturesThis means less time wasted repositioning probes

Astrometric Triangulation IV: Reduces scan time by 10%Especially important when tracking down shipsIt takes less time to receive scan results from your probes

Astrometric Acquisition IV: 5% stronger signal strength per levelThis might allow you to get 100% signal strength of a target with larger probing ranges, saving time

It uses the same system as regular probing for exploration sitesThe only real differences are that you will find much more signatures and that those signatures are mobile, so it's easier to lose the signature, especially if the target is aware you are probing for him/her

It's worth noting that drones or probes are very hard to track down and may require some skill investment to optimize the signal strengthIt's also harder to find exploration sites with combat probes, it's preferred to load Core Scanner probes if that is the target

UsesShip probing is used for several reasonsHere is a few popular uses below:

To track a target who is hiding in a safe zone or mission deadspace (PvP)

To find a mission deadspace and ninja loot or/and ninja salvage the wrecks in there
Find abandoned drones or probes
