Boom-mounted airborne magnetic and electromagnetic data sets provide complementary information regarding a site, whether the primary purpose of the investigation is to map and locate munitions or other buried metals, or to characterize shallow geologic features. Current boom-mounted systems are described along with distinctives of these systems for geologic mapping and metal detection. Observed falloff in sensitivity of both types of systems with respect to altitude is summarized. Several examples are provided that demonstrate the benefits of joint magnetic and electromagnetic surveys with boom-mounted systems.
