✔️Advantages of Magnetometers Locating

What are the Advantages of Magnetic/Magnetometers Locating? Advantages of Magnetic locators are the specific ability to only detect ferrous metals, portability, ease of use and availability and affordability to purchase.

Here is a list of some more advantages and context for utility locating.

🎯 Highly Sensitive to Ferrous Metals, not alloys: They can detect ferromagnetic metals and their alloys.

The magnetometer sensors, which collect ambient magnetic forces, are not subject to the same interference as ground penetrating radar. 📡

Magnetics typically can detect through certain interference that would limit other geophysical methods.

For example, a steel tank at an unknown location beneath a paved parking lot (reinforced with wire mesh or rods) can be identified using a magnetometer.  A magnetometer would be able to locate the tank since its magnetic field would be greater than that of the reinforcement material.

Non-destructive: Allows for the detection of underground objects without the need for excavation.

⚖️ Magnetic values often provide some indication of relative mass, i.e., large mass versus small mass.

😌 Ease of Use: Generally lightweight and easy to operate, requiring minimal training. Most systems, can obtain data at a walking pace (or faster), allowing an area of several acres to be surveyed in a day.
Newer magnetometer systems have been designed with a direct input for GPS. 

Durability: Designed for field use, magnetic locators are built to withstand rough handling and various environmental conditions.

📌Most systems and support equipment (measuring tapes, GPS units, and flagging) can easily be transported in the trunk of a car or van. Systems are non-invasive, mobile, and self-contained. 

🔋 No external power or additional connections are needed. 

👉 Availability: Magnetometer systems are widely available for purchase or rental.
