Hi Marchal,

       If you go to http://www.geoinstr.com/ and look under accelerometers 
you should find the 220 listed. It is rated at 2.25 V / g from DC to 50 Hz. 
Why not ask Geospace for details? Since power supplies are quoted, this does 
not sound like a simple coil / sensor type of instrument.
       
       Regards,

       Chris Chapman

ly I have bought an used Geotech SL 220, now I would like

to use the SL 220, just like my Lehman.

So, does anyone have any experience with a horizontal Geotech SL 220 

and running it with Larry's filt/amp and 16 bit A/D?
