Metal Detector Pinpointing Accuracy Under Field Conditions

As ordnance and landmine-detection technology advances, mine-action organizations across the world are increasingly using more sophisticated types of metal detectors. Each metal detector contains its own strengths and weaknesses, and until now, no accurate way exists to quantify the differences between the models. In this article, a method is shown to successfully evaluate metal-detector accuracy in a controlled field condition and provides data on the differences between single coil, double-D coil and other metal-detector types. The International Test and Evaluation Program for Humanitarian Demining conducted the 2009 evaluation in Germany that provides the data used in this article.
