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.

Omni Marker’s patented three orthogonal circuits are what create the unique spherical field

Omni Marker spherical field compared to the standard 3M Ball Marker dipole field.

Advantages of Omni Markers

• Easily installed without specific angle/direction.
• Lightweight, with no hazardous chemicals. The Omni Marker contains no floating or moving parts or chemicals. This eliminates the need for material safety data sheets
• The Omni Marker’s durable, lightweight design keeps your shipping and storage costs low while giving you years of reliable service.
