Probe is a 1972 American made-for-television crime sci-fi thriller film produced as a pilot for a science fiction detective series, originally to have continued under that title. Created by Leslie Stevens, it starred Hugh O'Brian as Hugh Lockwood, one of a group of high-tech private eyes working for the organization "World Securities Corp." When picked up for series production, the title was changed to Search, because Probe was the name of an existing PBS series. The film originally aired February 21, 1972 on NBC.The investigators, called Probes, were outfitted with various electronic implants including a button-sized "scanner" containing a miniaturized video camera, microphone and transmitter linked to a team of technicians and experts who constantly monitored the Probe's surroundings, actions and vital signs; they were able to supply the Probe with encyclopedic information on any subject.

Lockwood was designated "Probe One." In the pilot, he sets out for Europe to track down a multimillion-pound stash of gemstones amassed by Hermann Goering during World War II.

The pilot has been released as a publish-on-demand DVD-R on August 1, 2011.
