Geostuff builds essential seismic accessories for near-surface exploration, including the AnySeis cableless seismic system, wall-lock borehole geophones (analog and digital), land streamers, and rollalong switches. The company was started by Doug Crice around 1990, initially building rollalong switches in his garage, and later developed mechanical wall-lock borehole geophones and commercial land streamers.
