Geofón is a sensitive omnidirectional geophone adapted for field recording. Originally designed for seismic measurements, it can be used with standard field recording equipment to capture very faint vibrations in various materials and even soil. It is now used by sound designers, musicians, field recordists and sound artists around the world. It comes in a waterproof plastic case, with a neodymium magnet, a spike and a suction cup.
⚠ 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
