Nexus Metal Detectors performance standards

An example of the depth capabilities of Nexus Standard SE:

Right:
The spade is exactly 40" long.

MINIMUM depth requirement for all Nexus metal detectors

The minimum requirements for depth penetration for all Nexus metal detectors
utilizing at least dual 6" search coil are:

14" (36 cm.) under compact normal soil in real conditions, for a large coin

10" (25 cm.) under compact normal soil in real conditions, for a small

MINIMUM discrimination requirements for all Nexus metal detectors

The minimum requirements for discrimination for all Nexus metal detectors,
regardless the search coil size or shape, is to be capable to distinguish beyond
any question between equal in size and mass metal objects, such as coins or
buttons, but different in alloy composition such as silver, bronze, lead, copper.

Any Nexus metal detector as mentioned above is to be capable of
discriminating lead against bronze, copper, silver; bronze against copper and
silver. In the same regard any less conductive alloy against alloy with higher
conductivity.
