Have just seen the most amazing documentary on the BBC concerning the application of geophysical techniques to a non developer funded investigation of an unknown cemetery within the heart of a world heritage urban site in the west of England. For those that missed out, apparently resistivity meters can now be re-calibrated in order to detect 2,000 year old fragments of wood and also to accurately map human skeletal remains down to the last bone. Had it not been on such a reputable channel, I would never have believed it. Tomorrow I will use the last of my departmental budget to buy this, obviously essential, new piece of survey kit. No excavation can now surely be without such a device.
Bit worried by the tone of the documentary though - seemed a bit too excitable. Surely archaeology is duller than this?
