HDD Beacons

HDD Beacons

Subsite® Electronics offers a versatile line of beacons to work with our broad range of HDD tool sizes and Subsite HDD Guidance Systems, including the 750, 752, 8500 and TK Series. These beacons are as durable as they are dependable in providing HDD bore-path data. Rubber end caps, secure HDD tool clocking contacts, and springs on battery fittings provide better protection from shock and vibration and enhance overall performance. And all of our beacons can be repaired, to help save you money.


  • Self-contained electronic pitch sensors eliminate the need for mechanical/electrical parts, resulting in improved reliability and more stable operation for smooth pitch readings.
  • The 86BG directional beacon measures and displays pitch in 0.1% increments.
  • Ditch Witch beacons are repairable.
  • Innovative design isolates beacons from high-pressure directional drilling fluids.
  • When used with the 752 tracker, the 86B beacon can transmit from depths of 0.3 to 50 feet (0.1 to 15.2 m); for deeper boring, the 86BH beacon provides readings to 70 feet (21.3 m) or more.*
  • Ditch Witch electronic guidance systems present beacon data in a clear, easy-to-understand LCD readout.
  • Equipped with quick-disconnect manifold so attachments can be changed without shutting off the machine.
  • All Ditch Witch directional beacons transmit roll angle, beacon temperature, beacon battery status, and pitch information as part of the horizontal directional drilling guidance system.
  • *Units are calibrated to these tolerances under test field conditions. Actual field conditions may cause signal distortions or may contain noise sources that result in depth estimates that vary from these figures.
