Whilst reading all the e-mails on MD I thought I would do a wee bit of
surfing on the net to see what capability the modern detectors have.
I was astonished by the CSCOPE CS9000HPX which according to the literature:
'The optimum object size detectable by the CS9000HPX is about 200 x 200 mm,
range 1 metre. Limit - up to 3 metres.'
How many plough soils go too such depths??
This is a serious stratigraphy trashing treasure finding machine, me thinks.
