173 (Footnote) The device is literally a tool designed to detect the presence of life, which is an IS-BE. This was a large electronic screen generator designed to permeate wide areas. To the ancient humans on Earth it resembled a sort of tree, since is consists of an interwoven lattice of electronic field generators and receivers. The electronic field detects the presence of IS-BEs, whether the IS-BE is occupying a body, or if they are outside a body. A portable version of this detection device was carried by each of the members of The Domain Search Party. Stone carvings in Sumeria show winged beings using pinecone-shaped instruments to scan the bodies of human beings. They are also shown carrying the power unit for the scanner which are depicted as stylized baskets or water buckets, being carried by eagle-headed, winged beings.
