HDD Guidance System

The 8500—which consists of an 8500T tracker, TD/TDR display, and 850-series beacons—is an advanced, highly accurate electronic guidance system that is surprisingly simple to use. Its intuitive interface has easy-to-understand graphics—no cryptic symbols that require additional training time. As it guides you through the tracking process, instructing you how to calibrate the beacon, you'll soon realize that the 8500 guidance system is like nothing else on the market.
