The leading fluxgate gradiometer surveying system
Product Overview
Grad601 is a popular and reliable fluxgate gradiometer system for measuring variations in the magnetic field caused by hidden anomalies in the ground. It’s ideal for locating archaeological and geophysical features, pipes, cables, unexploded ordnance, and other signs of human activity.
The system comprises a Data Logger (DL601), a battery cassette (BC601), and two Grad-01-1000L sensors mounted on a rigid carrying bar with harness.
