When you are in the market for a magnetic utility locator, you should start by assessing your targeting and detection needs. Some magnetic locators are optimized to locate property markers, survey pins and water and gas valves, while others are used to locate unexploded ordnance. Learn how to select the right locator for any underground detection task and find out more about the leading Schonstedt magnetic locator systems.
Select an Underground Target
The underground target that you need to detect will determine the best magnetic locator for the job. These tools are useful for finding ferrous materials such as rebar marking property corners, septic tank lid handles, ductile iron pipe and cast iron meter and valve boxes. Locator signals are strongest when detecting large objects at relatively shallow depth.
Once you know what you are trying to identify underground, you can select a magnetic locator model based on the detection range, sensitivity and target definition. A number of brands make magnetic locators, but a Schonstedt locator is an excellent choice for most underground detection tasks. Some models are optimized for locating survey pins, markers, nails, valves and manhole covers.
Schonstedt Magnetic Locator Features
Magnetic locators made by Schonstedt feature a variety of options for different detection needs. The GA-52Cx Magnetic Locator with Hard Case is a powerful detector suitable for a wide range of applications. The GA-52Cx model features five sensitivity settings, a piezoelectric speaker and modular, all solid state construction in aluminum casing.
Schonstedt also makes the more rugged GA-72Cd magnetic locator and the Maggie and Spot magnetic locators. Maggie is an ergonomic, single-handed locator that is resistant to dust and water exposure. Spot is made for rough terrain and has a range up to 18 feet deep based on the target. The design and weight of these models varies, as do modes of signal indication. Some magnetic locators provide both audio and visual signals for precisely locating targets. Other locators provide audio indications and enable users to set the volume or choose between nulling or peaking options.
Magnetic vs Cable Locators
Magnetic locators work by measuring the magnetic field distortion surrounding buried metal targets rather than emitting signals like a utility locator. Magnetism is the only mode of detection possible with a magnetic locator, which means that a magnetic locator is not the most useful option for finding non-ferrous metal.
Cable locators activate an electromagnetic field created by electrical current. This type of location tool can be operated in passive location mode if live current is present or perform active location through induction or connection. Utility locators are helpful for finding other types of metals such as aluminum and copper in addition to iron and steel based on the frequencies supported by a system.
Your detection needs will determine which type of locating tool you should use. You can browse a full selection of Schonstedt magnetic locator models and cable locators to find the right locator for any underground detection task. Review the features of any model you are considering to select the best locator for any task.
