ShockWatch 2 impact indicators are single-use, go/no-go devices that determine if fragile products have been dropped during transit or in storage. The indicators are field-armable, tamperproof devices that turn bright red when an impact beyond a specific threshold has occurred.

Each ShockWatch 2 has a unique identifier to support traceability. ShockWatch 2 is a patented product, covered by US Patent No. 8,234,994 and No. 9,423,312.
