       I shure hope so. Larry has just sold me a triaxial unit...! Seems to 
work well.

       Short answer is that some of the higher frequency units (>14 Hz?), 
that you might not want to use for seismometry, can be operated in any 
position. The lower frequency units may be produced in horizontal and 
vertical versions - the HS-10 requires an orientation to 5 or 10 deg 
depending on the model. The springs inside are different for h & v models. 
Have a look at the specs on http://www.geospacelp.com/
