The Latitude 12 Rugged Tablet is certified MIL-STD-810G for everything from drop height to tactical standby and solar radiation. It can operate in extremes from -29C to 63C. It also carries IP-65 ingress protection, MIL-STD-461F electromagnetic interference, and ANSI/ISA.12.12.01 hazardous location certifications. It's very rugged, and while the certifications are on paper, I did have a chance to use one as a real-time GPS enabled map strapped to a jet ski. It survived hours and hours of intense water, sun, and vibration. Today I am not evaluating its ruggedness, but instead its performance.
