The Omni Marker electronically marks and locates underground facilities. The patented device contains three orthogonal tuned circuits. When excited by a standard marker locator, these passive circuits produce a uniform, spherical RF field in every direction. According to the manufacturer, it provides 25% greater range than 4-in. ball markers. It produces a wide field that is easy to find months or years later, with a signal peak directly above the marker for precise location within inches.
Because it produces a spherical field, the marker does not require any particular orientation when buried. As a result, there's no need for it to be level in the ground like flat-style electronic markers. Just toss it into the trench or excavation and cover it up with a normal backfill. Even though it is 4 ½-in.-dia. at its widest point, its shape allows it to fit easily into a standard 4-in. trench with no extra digging. It contains no batteries or active components, and the reliable design means the markers will last as long as a buried plant. The marker locates the following:
Buried splices and load coils
Buried service drops
Fiber optic facilities
Manholes under pavement or grade changes
Snow covered installations
