Morphology

metal + detector

The meaning is directly and transparently derived from the constituents: 'metal' (the substance) + 'detector' (an instrument that detects), so a device that detects metal. This noun–noun composition follows a common, cross-linguistically familiar pattern (e.g. Spanish 'detector de metales'), making it immediately inferable by a B1 learner who knows both words.

Etymology

Metal detector is a small machine you sweep over the ground or people and it beeps when it is near metal. Because of that clear image of sweeping and a beep, it means 'a device that finds hidden or unwanted metal'.
