RF Marker Balls - Buried utility marker detectable from surface with locator

Omni Marker provides an improved method to electronically mark and locate underground facilities. Unlike other marking devices that use just a single coil, the Omni Marker contains three orthogonal tuned circuits.

When excited by any standard marker locator, these passive circuits produce a uniform, spherical RF field in every direction. Because of their unique patented design, the Omni Marker offers benefits that are superior to any other electronic marking system.

It produces a wider field that is easy to find months or years later, with a signal peak directly above the marker for precise location within inches.
