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?
