Schonstedt GA-72Cd Magnetic Locator

Precision Ferrous Metal Detection with Visual + Audio Target Confirmation

Details

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.

Key Features

  • Visual + Audio Detection
    Audible signal pitch increases with target strength, while a digital bar graph confirms polarity and magnitude for fast, confident location.

  • High Sensitivity with Deep Detection
    Locates ferrous objects up to 16 feet deep (depending on size, shape, and orientation)—ideal for critical infrastructure and buried utility components.

  • Polarity Indication
    Understand the alignment of buried targets. The GA-72Cd’s polarity readout helps distinguish between horizontal and vertical orientations.

  • Tough, Waterproof Construction
    Fully sealed, weather-resistant design with aluminum sensor tubes and ABS housing. Rated for field use in rain, snow, and dusty job sites.
  • Intuitive Operation
    Simple keypad controls and ergonomic balance reduce training time and field fatigue. Adjustable sensitivity ensures accurate detection in varied conditions.

How It Works

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.

Why Field Crews Choose the GA-72Cd

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.
