What is the advantage of a none motion mode?

[FORUM XP]

DEUS is designed to operate most of the time in motion mode, which means that a metal target will only be detected if the detector’s coil is moving. However, the detector can also be operated in none motion mode(pinpoint), if required, which means that it will detect even if the coil is motionless above a target.

In modern detectors, none motion is most often used to locate a target more precisely (pinpointing).
However this mode is also very useful for detecting the presence of metal in cramped locations, where there is not enough space to swing the coil, or if there is too much interference from other metals around or close to the target. For example, locating hiding places inside houses, cellars and walls.
None motion mode is also widely used in the construction industry to locate metal pipes, as it enables them to be continually tracked.
