Precision Ferrous Metal Detection with Visual + Audio Target Confirmation
The Schonstedt GA-72Cd combines deep magnetic detection with dual feedback—providing both audio tone and a digital bar graph to help field crews quickly identify and verify buried iron and steel objects. Trusted by surveyors, utility locators, construction crews, and military UXO teams, the GA-72Cd builds on the same rugged principles as the GA-52Cx while offering enhanced visual target feedback for added confidence. Whether you're locating valve covers, manhole lids, or survey markers, the GA-72Cd’s rugged build and advanced interface give you an edge in the field.
Like all Schonstedt magnetic locators, the GA-72Cd operates using the principle of magnetic gradient detection. Two sensors spaced at a fixed distance continuously measure Earth’s magnetic field. A buried ferrous object—such as a steel pipe or iron cover—causes a distortion in the field, producing a gradient.
The GA-72Cd detects that gradient and alerts users through both an increasing audio pitch and a bar graph on the LCD screen. The bar graph not only confirms the presence of a magnetic anomaly but also shows the polarity, helping operators distinguish whether an object is aligned horizontally or vertically—an advantage when tracking elongated buried structures.
Performing overlapping sweeps in an “X” pattern helps quickly pinpoint the object’s exact location. Sensitivity can be adjusted to filter out shallow interference and dial in on deeper or smaller targets.
The GA-72Cd provides a step up in user feedback without sacrificing rugged simplicity. It’s a workhorse tool that balances ease of use, accuracy, and field-durable construction. The addition of a digital readout makes it ideal for crews that require confirmation of signal polarity or want faster verification of buried objects in complex job sites.
No boot-up time. No calibration. Just power on, sweep, and locate.
We supply the GA-72Cd to contractors, surveyors, and municipalities who demand reliable performance with every scan.
