Our drone-based platforms and processing software are developed for delivering high-quality subsurface magnetic data to detect hidden manmade objects and geological structures. This is relevant e.g. for mapping in former and ongoing war zones or identifying oil barrels, pipelines, hidden archaeology and within natural resource exploration. Our platforms deliver high-quality data over land as well as over lakes and coastal waters at water depths up to 7 meters. The unique and patent pending attachment system stabilizes the magnetic sensors, which makes our system ideal for surveying close to the surface and, hence, for targeting small ferrous objects or for surveying in hilly and mountainous terrains.
