As a Standard Action, a Use Computer check lets you hear or see other targets or detect someone or something sneaking up on you from behind. If the target is actively attempting to remain undetected, your Use Computer check is opposed by the target's Stealth check.
If the target is not making any special effort to avoid detection, the Use Computer check DC is determined by the target's size:
| TARGET SIZE | DC | TARGET SIZE | DC | |
|---|---|---|---|---|
| Colossal | -15 | Huge | -5 | |
| Gargantuan | -10 | Large | 0 |
On Starship Scale maps, your Use Computer check has a -5 penalty for every 10 squares between you and the target, and you take a -5 penalty on your check if attempting to detect a target that is powered down or otherwise not emitting an energy signature.
Obstacles, Cloaking Devices, Jammers, and sensor masks can also impose penalties.
