"...I told you that this tech was not CDEx's quite/quiet/quit a long time ago." The orginal, <b>revolutionary</b> Loch/CDEX tech was about trace detection of explosives at great stand-off distances in near real time. It was NOT about standard UVF detection of bulk chemicals at under an inch in pristine laboratory conditions. It appears that the meth gun will be the closes Loch/CDEx is going to come to anything that even comes close to what was originally advertsied.
