Hi Geoff,

       I would not expect the sensitivity to change more than a few % with 
temperature.

       I do not have to operating range for a L15B, but typcial operation of 
geophones may be from -20 F to 160F. If you dig a nice cosy hole for it, you 
won't see any temperature extremes. 

       Regards,

       Chris Chapman

Hi Geoff,

       I would not expect the sensitivity to c= hange more than a few % with temperature.

       I do not have to operating range for a=20= L15B, but typcial operation of geophones may be from -20 F to 160F. If you d= ig a nice cosy hole for it, you won't see any temperature extremes.
