Abstract: This disclosure relates generally to apparatus, systems, and methods for boring in earth or other environments, both manmade and natural. More specifically, but not exclusively, the disclosure relates to devices and methods for inspecting the path of a bore (e.g., including horizontal, angular, vertical bores in 3-dimensional space) to detect any damage caused by the boring activity to infrastructure in the path of the bore. Such infrastructure may include, but not by way of limitation, gas lines, sewer lines, communication lines (e.g., fiber optic lines), electric lines, and other infrastructure. The disclosure further relates to devices and methods for mapping locations of underground objects, geological compositions, and other detectable underground features.

Abstract: Apparatus for magnetically sensing, computing, and displaying cable distance, as well as computing and displaying other user-selectable information in a pipe inspection system or other system is disclosed. Two or more permanent magnets may be mounted in spaced apart fashion, on either a frame or a rotatable member supported on the frame for rotation about an axis. A magnetic sensor may be mounted on the other one of the rotatable member or frame on which the magnets are not mounted, so that either the magnets rotate around the magnetic sensor or the magnetic sensor rotates between the permanent magnets. The magnetic sensor may generate output signals representing changes in at least two axes in a composite magnetic field generated by the permanent magnets.
