Geophone Element

  • High sensitivity geophone 4.5Hz , 5Hz

High sensitivity geophone 4.5Hz , 5Hz

High sensitivity geophone 4.5Hz , 5Hz 

The High Sensitivity geophone is used to receive the weak deep and low frequency signal. This kind of geophone has following characters: Low frequency, Low distortion and high sensitivity.

It’s suitable for field single point data acquisition.

It can be used as single point and also 3- component.
