As a HAM radio operator I am always on the prowl for cool and useful electronic gadgets. Especially gadgets that can help me snoop out offending RF energy flowing out of my radios and back into shack electronics. There are almost as many ways of isolating and tracking down offending rf producers as there are companies who make hack devices to try and do it. Those companies concentrate on novelty, the novelty of having a device that will beep when near RF. Well this bad boy does what it says its designed to do. It accurately pointed out and led me to a GPS sending unit in two different handheld radios I had my daughters place around the property. This thing literally pointed me right to them and from across the back yard when on high sensitivity. It located every sort of radio transmitter signal I could throw at it. The auto mode is pretty slick, pretty much set, forget and as an operator you only need to adjust sensitivity and work your path to the device. Now, for my specific application, locating rf causing issues in my shack. Within a few seconds of standing at my desk I was able to identify a monitor cable that was literally carrying almost as much rf when transmitting as one of the antenna feed lines. Ironically, this monitor would periodically display the osd and or adjust brightness on its own. After the cable swap. all has been quiet. After a good 45 minutes of scanning the shack I was able to pinpoint the source of a buzzing sound I had been hearing on 2m signals. I thought it was antenna related but alas, turns out the power injector for a nearby wireless access point. Prior to buying this detector my only means of checking for where the bad signal was coming from was by individually powering down the circuits one at a time then devices themselves on each circuit. In this case, I powered down the WAP but never thought to unplug the injector so the interference didn't seem to be coming from the WAP. Well, it was coming from the injector and this device located the issue by pointing me to spurious RF caused here. Ultimately, the real test was individually measuring the rf flowing out of the radio and back into the power plane of the shack. Found multiple cables that needed ferrite bead and once installed, my uninterruptible power supply no longer tripped when broadcasting with more than 50 watts. So, while I didn't use this awesome device as a "spy" gadget, I did have great success with it at being a HAM radio operator tool and highly recommend this for anyone serious about tracking down RF signals.

Just as described

I was pleased with the sensitivity of the detector. It is very effective for detecting RF signals like wifi, cellphones and the electromagnetic sensor does work (although the sensor must be nearby the magnet). The camera detector is functional but must be used very close to work effectively. Considering the price is so low this is a practical gadget for some electronic counter-surveillance capabilities. After researching the technique and familiarizing myself with the controls my initial testing confirms this device would be effective for sweeping areas that should not have RF signals to indicate that something which shouldn't be there is broadcasting. I would recommend turning off all broadcasting devices and then sweeping on very low sensitivity. It will show you "hot spots" where the signal is detected. As you get closer to the amplitude the reading will intensify indicating which direction to look for RF devices.The instructions for AI mode say it will continuously beep if a signal with intensity above 8 is detected. This seems like an amplitude measurement for signal strength as it will trip if brought near enough to any wifi device. Unfortunately, it has no method to differentiate between different signals frequency/classification within the device. As it stands now I consider this a useful device for locating hidden devices but in an urban area you will have many false positives from UEE and benign broadcasting devices like neighbors wifi routers. I am curious if there is any method to output the data collected from the AI mode because this would greatly expand the capabilities for a very reasonably priced product.AI functionality is intriguing but underutilized.My recommendation for making a more effective product would be some method for outputting data from the device to facilitate analysis. Overall, a very nice device that does what it says.

This device looks more like an elaborate tool, some time of spy gadget with sounds and lights. Does it work, yes, but depending on what you are looking for. It did a great job of detecting the signal shooting out of the router and several range extenders. It did a poor job of detecting cameras.The problem with the instructions is that it fails to tell you that after turning the device on, you can adjust the sensitivity level by continuing to turn the dial, or at least I assume that to be the case just fiddling with it in front of my router - see that's the problem, is my assumption correct? Because if you turn it up, you can get a false sense of signal that may not be there because you can actually make the device go into red, beep and vibrate by turning the knob.Additionally, while the instructions tell you the button functions, the instructions fail to explain exactly which source or when to use specific buttons. For example, the camera detection has to intensity levels of lights, one blinks fast, one does not - which one do you use? Also, the instructions use inproper grammar making it more difficult to understand the reading.All in all - I was able to confirm my router was there, but I didn't need a detector to take me there. I could not confirm, nor would I trust this tool to accurately detect any listing device signals or hidden cameras which is what I was hoping it would do. Given the instructions and the guessing game of the functions, I have little belief or trust in the product to do what it says it can do.
