Dewayne,


Geophones are used to record local events. 1 Hz sensors will pick up the
P wave of a teleseismic event but other then that they do a bad job at
recording the lower frequence waves observed from distant event. See my
geophone page here

I have seen the message about the geophones that are for sale.


My knowledge of geophones is equal to my knowledge of the women

I currently have a homebrew Lehman. With it I can record any

5.8 event world wide. How does one of the geophones compare with

a lehman?
