Please remember that our detectors do NOT work "stand-alone" but must be connected to a computer, running our Rad software in order to operate. You should be comfortable with installing software and USB drivers on your computer, before ordering a detector.

Also note that the mica window on the geiger tube is extremely fragile, and the detector must be handled with care. The detectors are only for inside use, not outside use, weather events will destroy them.
