The drill head position is determined by reading
beacon roll. Roll is displayed as a clock face
position.

2. Slowly rotate pipe until locator displays desired
beacon roll.
To change direction:
1. Rotate pipe to clock position you intend to travel.
2. Push pipe into ground.
To move forward without changing direction:
Rotate pipe into ground.
Record Bore Path
Locate drill head every half-length of pipe. As the job is completed, record the actual data for each drill
pipe. List pitch and depth of each joint and a brief description of the procedure. In addition, draw a simple
sketch of the site and record depth and rough location of pullback.
The Trac Management System Plus is also available for plotting and tracking your bore path. It utilizes the
750 Tracker, 750 Display, a tracking beacon, and special software. The display can store jobs in its
memory or the system can be run in the field using a laptop computer equipped with the Windows
®
95 or
higher operating system. See your Ditch Witch dealer for details.
