The Seba Marker MAR 100-3D provides a new and better way to
mark and locate underground facilities. Unlike other marking
devices with a single coil, the MAR 100-3D contains three
orthogonal tuned circuits. When excited by a standard marker
locator, these passive circuits produce a uniform, spherical RF field in every direction. Because of this unique patented design, the Seba Marker MAR 100-3D offers benefits that are superior to any other electronic marking system. |
