A Dunlop was a type of handheld metal detector used by CTU agents.
When meeting with Jonathan Wallace at Studio City during Day 2, Jack Bauer used a Dunlop to check him for weapons. Wallace identified the equipment and told Jack that it would pick up a piece of shrapnel in his ribcage. However, it was actually a computer chip that Wallace had implanted in himself, containing evidence that the Cyprus recording was fake. ("Day 2: 12:00am-1:00am")
