ParaTrack 1 is the first generation, standard utilized for many years in the HDD industry. This system uses DC current to create a magnetic field that the steering tool can locate off of. With ParaTrack 1 you also have the additional option of running the surface coil in previously drilled bores for locating. This is ideal if previous bores are located parallel of the running bore. ParaTrack 1 is slower than ParaTrack 2 in locating but does utilize current technology and can use first generation DC current tools currently available on the market.
