Founded in 1990 and based in Kent, Washington, Digital Control Incorporated (DCI) specialises in advanced Horizontal Directional Drilling (HDD) locating and tracking systems. The company designs and makes the DigiTrak Falcon F5, F2, and TeraTrak R1 bore planning tools, alongside remote displays and drilling fluid systems. These products go to work installing underground utilities - fibre optics, power, water - with minimal environmental impact. The global HDD industry is the customer base, and DCI's solutions combine electrical engineering, embedded systems, and mobile app development for iOS and Android, with virtual reality training tools among the more recent innovations. Made-in-the-USA is a deliberate stance (US parts and US labour), backed by world-class customer support and training. SEQ Drilling and Electric Conduit Construction are among the clients. Cutting-edge technology, reliability, and sustainability in underground construction are the company's recurring themes.
