The Tempest has undergone extensive tests in Cambodia for AP and AT mines. Tempest machines are continuously being used in the field by MAG and The Halo Trust. The U.S. Army has tested Tempest in the United States and abroad.
In April 2005, the Tempest Mark 5 was tested by QinetiQ, a leading UK-based defence and security technology company. During the trial the standard vegetation flail head, the slasher and the large magnet were assessed. QinetiQ reported: “The machine has the ability to clear both mines and vegetation.”
