DITCH WITCH® ELECTRONICS 8500 Guidance system The 8500—which consists of an 8500T tracker, 8500D 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. The 8500 tracking system provides three ways to locate a beacon using walkover location mode. Choose which method to use based on your tracking situation: 1) Single-point Location—use to find general location of beacon; 2) Peak Location— use to position tracker over beacon if beacon depth is greater than 30 ft (9 m); or 3) Advanced Location—use to position tracker over beacon if beacon depth is less than 30 ft (9 m). KEY FEATURES Icon- and menu-driven screens are intuitive and easy to navigate; straightforward onscreen graphics reduce training time. Ultra-low, 1.75-kHz frequency can “see through” signals from nearby objects, such as rebar and overhead power lines. Offset locating and depth-reading ability—an exclusive feature— helps determine depth and horizontal offset alongside the beacon. For bores requiring less accuracy, operational speed can be improved with the “drill-thru” mode, which allows you to place the tracker at a given point and drill to and beyond it on a calculated path. Provides true depth readings on inclines of up to 20 percent, so you can track up the sides of ditches and over uneven terrain. With 60 roll positions on the clockface, you have access to more detailed information, resulting in a more accurate bore. Soft-touch hand grips and balanced weight help make the 8500 easy to use over the course of a long day. ditchwitch.com
