Geometrics' Magnetometers - Land, Sea, and Air

Geometrics’ magnetometers have been the instrument of choice by every discipline imaginable. Geometrics’ core line of air, sea and land magnetometers are built to last under the most extreme climates and survey conditions. From the very beginning, in 1968, Geometrics’ magnetometers have consistently delivered value and performance to the geophysical engineering community. Geophysicists demand reliability, performance, and after-sales support for their instruments and have learned that this is what they can expect with Geometrics’ magnetometers.
