Does anyone know what this high tech equipment is that anthropologist, Harn, is recommending that LE bring in to use in the search for Stacy? I've read that archeologists have some sort of equipment they use prior to any sort of excavation to determine the location of an ancient buried village. But what exactly does this equipment see? Can it see a human skeleton? Or is it limited to only seeing artificial outlines indicating a man-made object or structure?

Locating Graves - Introduction
Ground penetrating radar surveys are useful for locating graves by detecting the buried coffin or vault. In cases where a vault or coffin does not exist, GeoModel, Inc. can examine the GPR data for disturbed soil or other remains of the burial. Remains of burials are easier to locate in sandy soils that do not contain tree roots or stones. Ground penetrating radar (GPR) is operated above the ground surface, and produces a cross-sectional image of the ground.
GeoModel, Inc. conducts GPR surveys for locating graves using a GPR digital control unit and antennas with frequencies of 400 or 900 MHz. Depths of investigation and the detail of the images observed are determined by the antenna that is used when conducting the survey and the soil type. A 400-MHz antenna will examine the subsurface to depths of up to 8 feet in sandy soils, but less deep in clayey soils. A higher frequency antenna (900-MHz or higher) can examine the near surface (up to 3 feet in depth) in greater detail.
