Gamma and neutron detection in a standard laptop-sized backpack, for covert threat detection with full control via mobile app.
Designed with public deployment in mind, the PackEye XS blends in amongst pedestrian crowds. All instrument data is available in the mobile app, which shows breadcrumb detection history on maps and sends data back to mission control.
The PackEye XS is the next generation after the PackEye He3 and GN2, at less than half the weight of the PackEye GN2 (3.65 kg versus 7.7 kg).
