Geofón DIY kit is a kit version of the Geofón, a sensitive omnidirectional geophone adjusted for field recording purposes. Originally designed for seismic measurements, it can be used with regular field recording equipment to capture very faint vibrations in various materials and even soil.
⚠ Neodymium magnets may cause interference with credit cards (magnetic stripes), cardiac pacemakers and ICDs.
⚠ Due to the nature of the geophone sensor, you may experience picking up electromagnetic interference in specific urban areas and other places with strong electromagnetic fields
