A Probity Probe was a type of Dark Detector that looked like a golden car antenna. It was waved in front of a person in order to detect concealment spells or hidden magical objects.[1]


In 1996, Arkie Philpott had a Probity Probe stuck up a certain location on his body during his attempt to withdraw money from Gringotts Wizarding Bank.[2]

On 1 September 1996, Argus Filch used one on the students coming into the school.[1]

When the Death Eaters took over Gringotts in 1997, they stationed guards outside the doors with Probity Probes. Harry Potter used a Confundus Charm on the Death Eaters from under the Invisibility Cloak during the Trio's break-in so that they wouldn't be discovered.[3]

During the late 2010s, members of the Statute of Secrecy Task Force used dark detectors, among them Probity Probes, to detect the chaotic magic caused by The Calamity.[4]

Possible uses

During the 1988–1989 school year, Jacob's sibling possibly used a Probity Probe to investigate the upstairs corridors.[5]

In 1995, Harry Potter might have had a Probity Probe used on him by Eric Munch whilst checking him into the Ministry of Magic before his hearing.[6]

Behind the scenes

  • Since the physical description of a Secrecy Sensor when Harry goes through the Atrium in book 5 and the Probity Probe the guards are equipped with by the front doors at Gringotts when Harry, Ron and Hermione infiltrate the bank in book 7 are similar, a Probity Probe may have been a type of Secrecy Sensor.
