Omni marker power 160. Electronically marks and relocates buried facilities. Unique design produces a uniform, spherical RF field in every direction. Easily located up to 5 ft away with any modern marker locator. Wider field with a signal peak directly above the marker provides precise location. Requires no particular orientation when buried. The Omni Marker provides greater range than 4-inch ball markers that use a dipole field. High-reliability design lasts as long as your buried plant. Colour coded by utility application.
