Looking for LRL working from 30/50 metres distance

[Tino-Italy]

Good afternoon everyone,

I am looking for a long range detector and I would like to know if anyone can design/produce a stand-alone (not hand held) long range detector suitable for detecting gold from a 30-50 metres height.

This is a serious enquiry which foresees the purchase of large quantities of such locators/detectors as well as the development of different detectors for other metals/minerals.

For a better idea of what I am looking for, please see my drawing below.

Thanks,
