PackEye XS Radiation Detection Backpack

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).

  • Patented NBR algorithm distinguishes natural background radiation from potential threats without sacrificing sensitivity
  • Fits in a standard laptop-sized bag – reduced size and weight for extended deployments and patrols
  • Fully controlled via the RadBridge mobile app (iOS and Android), with alerts and alarms to headphones or smartwatch
  • Connects to RadEye SPRD instruments in the app to begin an ID evaluation without opening the backpack
  • Automatically collates instrument data for review, export or reachback via Rad or CBRNe Responder
