Sam Fisher- EM Vision

  He switched his goggles to IR and studied the floor above. He saw no man-shaped hot spots. He switched to EM, or Electro-Magnetic. In the swirling blue-black image, two objects immediately caught his eye, each pulsing with its own EM signature. One was attached to the inside of the office door, the other opposite it, on a filing cabinet. There was no mistaking what he was seeing: a laser-beam trigger and some kind of shaped explosive charge. Open the door, the beam is severed, the charge detonates.

  He considered his options. Defeating the wall mine was possible, but iffy. The windows were out as well. Anyone sophisticated enough to employ this type of booby trap would also have
the windows covered.
