Save valuable time and minimize the risk of expensive utility damage by using the Spike Marker from Tempo to identify underground utility locations. Designed to mark buried infrastructure up to one meter (3.3 feet) below the surface, Spike Markers are especially effective for locating distribution ducts and similar installations—such as fiber and cable TV drops, traffic signal control wires, or residential lines for gas, electricity, and district heating. Their compact size and narrow diameter make them a practical alternative in spaces where larger solutions like the Tempo OmniMarker II aren’t suitable. Their smaller footprint also allows for easy integration into tight or overgrown enclosures, simplifying future identification and relocation. Manufactured from durable high-density polyethylene (HDPE), the Spike Marker offers a lifespan that matches the longevity of the utility systems it’s buried with. It is compatible with nearly all marker locator systems, including Tempo’s EML-100, and is available in a range of standard industry frequencies and color options.
