Skywest uses the newest technology available from the Vivid-Metrotech company.

Electromagnetic utility locators are used for tracing metallic pipes, gas lines and utility cables in drilling and excavation locations. These utility locators consist of a separate transmitter and receiver. The transmitter emits a radio frequency (Electromagnetic field) that induces secondary fields in nearby metallic pipes and cables. The receiver detects these fields and accurately locates and traces the pipes, often to distances over 200 m from the transmitter. Electromagnetic locating is by far the most reliable technology for detecting metallic pipes and cables and provides accurate location and detection.
