What is the possibility of obtaining “false positives†with GT200?
False positives are problems in all known detection equipment in service today. Similarly, as with drug urine test, some suspects who are known to have taken medication with codeine may show positive results. A manageable amount of false positives are generally incorporated into the continuing operation of detection equipment and can range from <1% to as high as 10% or more. The key to understanding to “False Positives†is to understand what causes detection equipment to “detect†a programmed substance that is not the actual substance. It is a known fact that certain chocolates and perfumes will cause IMS equipment to (a different technology from GT200) to detect such item as explosive. Due to the nature of the technology upon which GT200 is built, it would be impossible for it to detect a substance that it is not programmed to detect. In other words, if the GT200 obtain a “lock†on an area for substance that the GT200 is searching for, and a "close-in" search using Canines or
