A metal detector is very nice, particularly when there isn’t a lot of aluminium in the ground. Archaeology cannot do without it. But what I really want now is a holographic radar instrument. Still in the prototype stage, this technology is being developed by Tim Bechtel of Franklin & Marshall College in Lancaster, Pennsylvania and colleagues, who primarily have land-mine removal in mind. It will image underground metal objects in 3D. Gimme gimme gimme!
And oh, how I hope that my country’s legislators will allow a responsible metal-detector hobby to develop here before holographic radar detectors hit the street.
