Geophones GS-100

GS-100

High Frequency Geophone

  • Small size, lightweight
  • High sensitivity, high output
  • Clean response to 600 Hz
  • Full one year warranty

The GS-100 is a high frequency, high output geophone with a natural frequency of 100 Hz. It has a clean band pass and minimum spurious response to 600 Hz.

Standard coil resistances are 600, 975, 1550 and 2300 ohms. Open circuit damping is 60% of critical.

The PC-21 Land Case is used with the GS-100 geophone.
