The Grad601 is a high-resolution fluxgate gradiometer. It is used for measuring minute variations in the magnetic field that are caused by hidden anomalies in the ground, such as archaeological features, pipes, cables or unexploded ordnance (UXO). The full system includes a data logger, a battery cassette, and either one or two Grad-01-1000L sensors mounted on a rigid carrying bar. Calibration is easy following an automated procedure.
The full system comprises a Data Logger (DL601), a battery cassette (BC601), and either one or two Grad-1000L sensors mounted on a rigid carrying bar together with a carrying harness (Grad601-2 only). Calibration is made easy via simple push-button control. The Data Logger’s non-volatile flash memory will hold surveyed grids. These can be downloaded as individual files, so different size grids may be recorded during a survey.
If you already use the Grad601, you can easily adapt your existing equipment to the Cart system, which can reduce update costs.
