| The Grad601-2 dual gradiometer includes an adjustable harness which completely relieves the operator's arms whilst carrying the instrument. |
| The prototype version of the probe being used by the GSC, contains two sets of 3-component magnetometers and the application of borehole magnetic gradiometer measurements are also being investigated. |
| An experiment to test this was performed by M. V. Moody and H. J. Paik in California with a three-axis superconducting gravity gradiometer that measured the gradients of gravity in three perpendicular directions. |
| Geophysics GPR developed a new three-dimensional helicopter borne magnetic gradiometer for surveys with limited ground clearance. |
| The group was awarded funding from the university to purchase a fluxgate gradiometer to conduct the survey. |
| One such invention was the rotating cruciform gravity gradiometer mass detector, which measures Earth's subsurface mass variations or gravitational multipole moments. |
