This unit contains a maximum of 12 pencil galvanometers in a block permanent magnet. They are driven by a bank of amplifiers to record seismic shot data from geophones. Two banks are usually required to give 24 channels of data from one seismic shot.The data is recorded on to a photo-sensitive paper strip, up to 4 or 5 seconds of data.
These units could be used in the field to collect data or at base to process corrected data.
Data would also be recorded on magnetic tape.
