Grad601 Single Axis Gradiometer
The Grad601 is a vertical component fluxgate gradiometer with data logger and either one or two cylindrical sensor assemblies for use in geophysics and archaeology.
Each Grad-01-1000L sensor contains two fluxgate magnetometers with a one metre vertical separation together with electronics and non-volatile memory for calibration data. The system provides an enhanced depth response, exceptional stability and electronic adjustment.

The Grad-01-1000L sensors can be supplied independently to create instruments with more than two sensors. Such multi-sensor systems can either be manually operated or pulled behind a vehicle, greatly increasing the surveying efficiency.
The Grad601-1 single sensor version is ideal for both archaeological prospection and the location of pipes, cables, drums, unexploded ordnance and archaeological features.
The Grad601-2 two-sensor version is designed for archaeological prospection and allows geophysical surveys to be completed in about half the time.

The exceptional temperature stability of the sensors ensures minimal drift during surveys and reduces the need for adjustment.
The Grad601 is supplied complete with cables and accessories in a rugged carrying case. The Grad601-2 dual gradiometer includes an adjustable harness which completely relieves the operator's arms whilst carrying the instrument.

ArcheoSurveyor is a powerful graphical mapping application for Windows PCs, specifically developed to meet the needs of today’s archaeological geophysicist. With it, you can download data directly from the Grad601 instrument (and many other commonly used geophysical survey instruments) or import from most file formats, assemble the resulting grids using intuitive drag-and-drop thumbnail images of the grids and apply a wide range of filters and operations to the data; modifying, removing or reordering any step at any time.

Important note on compatibility:
ArcheoSurveyor version 2 must be used to ensure full compatibility with new Grad601 instruments (and old instruments upgraded to v6.6 firmware).
ArcheoSurveyor version 1 cannot correctly read data directly from new or upgraded Grad601 instruments.
The following short video demonstrates how simple it is to assembly and set-up the Grad601
