"Sonic probe" was a general term used to describe sonic screwdrivers and similar devices. It was a term applied by both Dalek Sec and the Sixth Doctor himself to the Doctor's sonic screwdriver. (TV: Doomsday, AUDIO: Apocalypse Element)

In an alternate timeline where she was trapped in Apalapucia for thirty-six years, Amy Pond insisted upon calling the sonic device she'd built a sonic probe in an attempt to sever all ties to the Eleventh Doctor and her travels with him. Her device had the ability to re-wire Handbots. When the Doctor took control of her "probe" to help bring two versions of Amy together, she finally admitted it was a screwdriver.
