 Subdynamic technicians are trained in every application of our services. Each technician, from our most seasoned crew member, to our most recent crew member, go through mandatory training programs, with required certifications in operating all Subdynamic equipment.  Subdynamic technicians can quickly identify issues such as reflected, absorbed, and diffused signals, and can quickly and confidently make the adjustments necessary to ensure a thorough locate for all our clients.

Electrical Active electrical with access to a service line, can be located and traced. All depths are Approx.

Communication — Active communication with access to line, can be located and traced. All depths are Approx.

Gas Active and non-active gas line can be located, with access. Gas line should be steel or with properly installed tracer wire. All depths are Approx.

Sanitary /storm line– Active and non-active sanitary and storm lines with access to line, can be located and traced only by physically inserting a cable or rod, with an attached transmitting device called a Sonde,  that emits a locatable signal that we can pick up above ground. All depths are Approx.,

Water / irrigation– These lines are non-traceable if the material is PVC (plastic).  Unless the pipe has a properly installed tracer wire, Locating usually stops at the end of the tracer wire. Alternate methods of tracing water/irrigation lines are frequently called a transonde to vibrate or “thumping” the water line. (call for more details)

Passive scans — Passive scanning techniques are excellent in open areas for finding unknown utilities. This method does not allow the operator to distinguish between the types Of utilities.

Radio scan Radio scans are typically found on a conductor of any type that is somehow receiving voltage, static, phone, radio, and any other unknown frequency, (depending on the strength of the signal, not all can be detected with this method)

Power scans– Power scans are typically used to determine if any 60 Hertz frequencies are present. 60 Hertz is the frequency standard for U.S. power. If a line is energized or “active”, it should show a power reading.

Induction scans– Induction scans are used to find unknown conductors and service lines found to have no access for a direct connection.

Magnetometer- Mag scans are used for shallow metallic utilities, unknown metal objects, and ambiguous metal structures and or anomalies. This tool is not usually used in tight scan areas or near reinforced concrete.
