These photos (a very small portion) are proofs of long distance metal detecting via radio. Reading messages of NJoseph about if is possible detect metal as radar via radio, yes, here a sample (maybe today is more difficult or impossible with this system for the intensive interference of all orders, include cellulars).
Read in the Dodge car Texas QDF - 819. Was in november 1985 (see the dates in the photos).
I'm collecting photos of 30 or more years about it. My next job is achieve 15 or 20 B&W photos of the years 1959 to the 60's. In these years the long distance detector was 2 tube radio in a wheelbarrow!!! and the lead-acid batteries in another wheelbarrow!!!
