We Stepped Up, So You Can Step Back

  • Highly Sensitive 2x2 NaI Detector

    Detects radiological threats from farther away, behind heavier shielding, and with better resolution than similarly sized RIDs.

  • Rugged Construction

    Drop-tested to 1m, completely enclosed crystal, and IP67-rated enclosure that protects against dust and water immersion up to 1m.

  • State-of-the-Art User Features

    360° EasyFinder Mode pinpoints and instructs operator on exact location of radiation source to keep responders and the community safe.
