The D3S ID is a powerful, wearable, unobtrusive and hands-free device which is continuously scanning for Gamma and Neutron radiation threats.

No one can see it in operation, or that you have found anything suspicious. You can go anywhere a terrorist could have gone and search areas quickly and efficiently. Unlike static or vehicle-mounted detectors, a person carrying a hidden detector is difficult to avoid and detect; literally, anyone could be carrying a D3S ID.
