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
Subsite 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

or higher operating system. See your Ditch Witch dealer for details.
