The electromagnetic Slingram method can provide three types of information simultaneously: 1) the apparent resistivity of the ground; 2) its apparent susceptibility; and 3) the characteristic signatures of buried metallic objects. To build an apparatus with these three measurement capabilities requires an appropriate choice of parameters, including frequency, coil separation, and coil orientation as well as calculations which take into account the electrical resistivity and the magnetic susceptibility of the ground. The value of the Slingram method for archaeological applications is shown by two examples: 1) a Gallo-Roman pottery workshop investigated with measurements of the apparent susceptibility using a reduced sampling wide mesh grid technique; and 2) the study of a Bronze hoard site located in a marsh. Capabilities of the Slingram method may be improved by further study of an apparatus using several receivers which would increase the depth of investigation. Use of several frequencies would overcome difficulties related to resolving the magnetic quadrature susceptibility. -- AATA
