Utility Locating Technology Comparison Questions and Answers.

Next we have, Magnetic locators, best questions and answers for utility locating Technology Comparison.

Here are the general facts about magnetic or magnetometers locators, to compare magnetic technology , for your situations, environments and availability on the market today for utility locating.

What are the Effort and training required for data interpretation?
It is Low to medium manufacture training, online courses, in-person field training and experience recommended.

What are the Specific Applications?
Its main attribute is to Detect ferrous metallic objects. like iron, iron alloys, steel, nickel but not non ferrous metals like aluminum, copper, brass, stainless steel.

What are the Specific Utilities that can be located?

Magnetic locators can locate the listed objects below, if they are made of ferromagnetic material. 

-Gas and water cast iron pipelines

-UST underground storage tanks (and their handles) 

-Septic, petrol, oil storage tanks

-Manhole covers

-Survey markers

-Utility pits

-Curb, valve, junction boxes


-Steel Drums

-30mm PK (Point Known) Nail 

💡 Knowing the material of your target can be valuable information,

It helps in choosing the right equipment and methods for utility locating, ensuring efficient and accurate work.
