Geophone - SM-24, with Insulating Disc

Need to put your finger on the pulse of the Earth? Did I just blow your mind? A geophone works by translating ground movement into voltage which can easily be read by a microcontroller. The SM-24 geophone element is designed to offer the highest performance in seismic exploration based upon field-proven I/O Sensor technology. Low distortion combined with excellent specifications provide high-fidelity data. Basically it's a super low frequency microphone for the ground.Perfect for all of your 2-D & 3-D seismic exploration needs with bandwidth from 10 Hz up to 240 Hz.
