  • MD with a strong focussed search field

    G'day,

    The "Elcometer P500 Imp Box Locator" metal detector
    http://www.elcometer.com/internation...pages/P500.htm
    claims in its advertising that it is a detector with "A strong focussed search field (that) ensures the accurate location of objects close to metal fencing and vehicles".

    If anyone here can provide an answer, I would like to know how this is achieved technically. Obviously it must have something to do with how the coil is designed and all I can think of is that it might simply be a conventional DD coil.

    It could also possibly be bogus advertising claims ... but if it could be done then I would think that its a technical improvement that should be employed by manufactures such as Whites on many of their detectors (especially on coin hunting MDs).

    Regards,
    Rob (RKC)

    Looking at the coil, it appears to be a mono-loop, so we can infer that this detector uses pulse-induction. Their claim of a strong focused search field most likely refers to the difference between a mono and a DD coil. The DD coil has a much wider scan. I don't think there is an technical breakthrough here.
