Magnetometers can detect large ferromagnetic bombs as deep as 6 m. They either measure vertical gradient using two fluxgates, or scalar vertical gradient using two Overhauser or Cesium magnetometers. Extremely precise tri-axial fluxgate gradiometer is described in Ref. . Magnetic sensors can also be used to find small ferromagnetic objects.

Alkali vapor optically pumped magnetometers use alkali metals including Cesium, Potassium or Rubidium. The cell containing the metal must be continuously heated to approximately 45 to 55 degrees Celsius to render the metal in gaseous form. These magnetometers operate on virtually the same principle as illustrated, in part, below.
In most archaeological applications the latter (gradiometer) configuration is preferred because it provides better resolution of small, near-surface phenomena. Magnetometers may also use a variety of different sensor types. Proton precession magnetometers have largely been superseded by faster and more sensitive fluxgate and cesium instruments.
