Re: FIDLERS

FIDLERS are made by Bicron.  Also, Alpha Spectra in Grand Junction custom
designs them.  Contact Frank Wilkinson at (800)231-2545.  However, I
thought the original posting had to do with using them for hot particle
detection?  I used them at Johnston Atoll for that very purpose (I already
sent a post to the requester about my experience).  They can detect hot
particles at the guideline, but only at the surface, anything more than 1
cm of coral/soil and detection becomes much more uncertain.
