  Subject: Comparison of available seismometers


  I am interested in acquiring a simple seismometer package for amateur =
use that is sensitive enough to detect teleseismic events. I would like =
to acquire a ready-to-use instrument rather than build something from =
scratch or from a kit. My main question is which seismometer to buy. I =
have come across the following instruments on the Web:

  AS-1 Amateur Seismologist (Jeff Batten) $550 ???
  http://www.amateurseismologist.com

  Vertical School Seismometer Ward=92s Natural Science $500
  =
http://www.wardsci.com/Product.asp_Q_cmss_E_seismometer_A_pn_E_IG0018602

  EQ-1 Next Generation Science $600
  http://www.nexgensci.com/store/pc/viewPrd.asp?idproduct=3D1

  Volksmeter II RLL Instruments (Zoltech) $995 single channel, $1495 =
dual channel
  (patented Symmetric Differential Capacitor (SDC) array sensor)
  http://www.rllinstruments.com

  In spite of the price difference, the Volksmeter seems interesting. As =
far as I an tell, it is based on recent technology that is different =
form the other three, which seem to be of the traditional Lehman type.

  Does anyone have any opinions or advice to give a rank beginner who =
has not been in a science classroom or lab in over 40 years?
