International pilot project for technology cooperation : final report ; a multi national technical evaluation of performance of commercial off the shelf metal detectors in the context of humanitarian demining The results of an evaluation of the detection performance for 29 commercial off the shelf (COTS) metal detectors against a range of low metal content anti personnel mines and some simulant targets are described in this report. This work was undertaken by organizations from four nations together with the European Commission in the International Pilot Project for Technology Co operation (IPPTC) in the Humanitarian Demining R&D environment. This report gives a summary of the methodologies and results. Detectors were assessed for performance in air; in a range of soils; and in realistic demining scenarios in Cambodia and Croatia. In addition the human factors aspect relating to the use of each detector was assessed.
