Certification

During the field tests of metal detection technology by OKM (also known as the "Future Series") several tests were conducted by Dr. Karl-Heinz Walker. He is an independent physicist and technical expert for measuring and sensor technologies, as well as a publicly certified expert of the IHK Karlsruhe (Chamber of Industry and Commerce).

All field tests were executed in July 2006. We supplied two of our best-selling products, the eXp 4000 as well as the Future 2005, to be reviewed by Dr. Walker, who picked some of the named devices by chance. The main reason for these reviews was to test the general trustworthiness and repeatability of the implemented detection technology we are using in our metal detectors.

With all selected products, the following tests have been performed:

• Metal detection of several metal objects (iron, aluminum, gold)
• Detection of underground voids (tunnels, plastic barrels)
• Reliability and performance tests (nearby detection, scan resolution, target depths)

After testing our metal detectors on different sites and under different environmental conditions, the technical expert Dr. Walker presented a final field test report and issued an official signed certificate.
