The good and the bad and the ugly of it
on February 8, 2014
The good: Well made. The case is black-anodized aluminum, not cheap plastic. The antenna is a standard whip as used on portable police and field radios, and attaches with a BNC connector, just as they do. Finding a replacement should be easy.
The ugly: The blue LED, which indicates the unit is on and flashes when the batteries are low, is WAY too bright. In fact, it makes a decent indoors flashlight. Unfortunately it is located just above the five red LEDs which light up successively to indicate the strength of a received signal. The LED is so bright that watching the much less bright red LEDs gave me a headache. I placed two colored stickers over it, and it is still too bright showing through those.
The bad: While it easily detected my wireless indoor phones when in use and my "emergency 9-1-1" pendant's base unit (which I was not aware broadcast RF continuously and see no reason why it should), it did NOT detect my hobby FM transmitter, which is emitting a powerful signal on a frequency well within the advertised range of this detector. Powering the transmitter up and down made no difference to the detector even when it was right next to the antenna. So, does it not detect FM? FM is just a type of modulation for a RF transmission, and this device is supposed to detect RF emissions. If it does not detect FM, then I would consider it useless as a serious bug detector.
Update 3/31/14: I sent the last few sentences above as a question to the manufacturer of this product on the same day I wrote the review. They responded by asking for the make/model information on the FM transmitter, which I provided to them. On 2/20, I wrote them again asking what they had found. The response was that they were working on it and "have not forgotten" me. I have not heard from them since. (Now August. Never heard from them.)
