Since 1973, General Digital Corporation has provided innovative design, development, and manufacturing solutions to the toughest of engineering challenges. Despite the numerous engineering companies that have come and gone in the last 50 years, General Digital’s dedication to quality American engineering has stood the test of time—from our VuePoint terminals released in the 1970s as one of the first available industrial touch screens, to our Tactical TwoView, a ruggedized MIL-certified workstation that was one of the first military-grade products to utilize USB-C. Our experienced electrical, mechanical, optical, and quality-control engineers (coupled with the power of our 50,000 sq. ft. manufacturing facility) allow us to tackle nearly any requirement.
