I am interested in acquiring a simple seismometer package for amateur=20
use that is sensitive enough to detect teleseismic events. I would like=20=

to acquire a ready-to-use instrument rather than build something from=20
scratch or from a kit. My main question is which seismometer to buy. I=20=

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=20=

dual channel
(patented Symmetric Differential Capacitor (SDC) array sensor)
http://www.rllinstruments.com

In spite of the price difference, the Volksmeter seems interesting. As=20=

far as I an tell, it is based on recent technology that is different=20
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=20=

not been in a science classroom or lab in over 40 years?
