Sometimes, in some floodplain situations, archaeological sites may be buried several meters deep beneath the current surface. The bucket auger is an essential piece of equipment, and with long sections of pipe added above the bucket may be safely extended to depths of up to seven meters (21 feet) to explore for buried archaeological sites.
