Modern explosive vapor detectors are designed to sniff out explosives hidden in luggage and other packages. Using hyper sensitive sensors the devices will detect small traces of explosive alerting security staff of hidden dangers with the package.
Handheld units are easily carried and operated; a short training session is all that is required to extend your security capability and protect life and property.
Beware of fake explosive detectors on the market costing lots of money but they do not detect anything. These detectors were sold throughout region and have contributed to many deaths. They are still being used in many places still putting lives at risk.
