How is the GT200 used for the searches of vehicles or high traffic areas?
Since the GT200 has the ability to detect substances from a very far distance, proper operational techniques must be used in conducting a vehicle road block search or when scanning an area where people are walking along a passageway. By sweeping a defined area in the path of travel (approximately 20-25 meters) and establishing a “clean area” , it is very simple and effective to scan the clean area as vehicles enter that area. By definition a “clean area” means that the background of the search area is not contaminated with the target substance. The GT200 will “lock” onto the first vehicles or persons that has the target substance. The GT200 antennae will stay and follow the target through the area for quick identification of any suspect substance being targeted.
