underground network passive marker
for underground networks
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.
