Omni Markers
The Tempo 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. (See Figure 31)

Omni Marker & Uni Marker Signals
Omni Markers and Uni Markers each emit a distinct type of signal as shown in
Figures 32 and 33. Omni Markers produce a uniform, spherical RF field in
every direction, while Uni Markers emit dipole field signals primarily up and
down. (See Figures 32 - 33)
