    This detector is not for beginners. If you are not familiar with radiation dosimetry, and do not have a working knowledge of EMF type radiations, this detector is not for you... Spend less on an entry level meter, and learn from there. NOW- if you are a professional... A building biologist, Radiation Dosimetrist, a well-informed, retired scientific investigator (such as myself), this detector is for you! This is much more accurate than the average $200 EMF meter, well worth the money if you want solid believable results! However, read the instructions thoroughly, and learn how to use all the meters functions in detail. If you learn to use the NFA1000, you will love it! Thumbs up for the professionals!

    Absolutely the 'best' meter I utilize measuring EMF's., which my customers deserve. I thank you all for offering the NFA1000 with a discount.
