Which ones do you have, the ADXL05s? They have two new 
models ADXL105 (replaced ADXL05) and ADXL202. I am 
wondering if these have better performance. Also, I am 
on the fault line in a quiet area, so I am wondering  
if that makes a difference. It is a complete waste of 
time trying these for strong motion?

Assuming that the ADXL devices are not useful, does 
anyone have any other recommendations for accelerometers
that would yield a better S/N ratio? Or any other 
strong motion sensor to complement my 1hz and 4.5hz
geophones?

Thanks,
Doug
