Hi.
What should be considered to detect metals in soil using a ~6 metres long x 5cm narrow coil, like
(=================================================================)
to be dragged transversally (up or down on the above sketch) in such way that will sweep a wide trail, instead of typical 30cm diametre round ones ?
Such coil to be lodged inside a 4" PVC pipe, driven by some proper circuitry [if possible]
Next Images just to show the concept, but much, much longer and narrowly shaped than :
