MariMag is a highly sensitive, accurate, and small size system for magnetic surveys both in shallow and deep water. Precise sensors with stable specifications as well as system module construction allow us to arrange both longitudinal and horizontal transverse gradiometers very easily. Special software from the equipment set can be installed on any personal computer. The software is intended for the equipment management and control, as well as data recording and visualization, and their upload in specified file formats.
