There is a large diffrence between a geophone with 24Hz natrual
frequancy and a sensor with 1Hz natrual frequancy.

The clicking noise problay is the mass in the sensor hitting the end of
the coil or the end of the housing.

I have not worked with this type of seismometer, but I do have two 4.5Hz
geophones to record earthquake.
