Question 1

Can this detect a phone?

Accepted Answer

Not fit for purpose. I had to return this item. It doesn't detect anything.YOU have to make it bleep yourself by turning the dial on to 180°maximum.It will then bleep. It doesn't do what it says on the description.

Question 2

Would this pick up a dictaphone device?

Accepted Answer

Hi，
Thanks for interesting our item, our reply as follows:
you can use RF Signal Detection Mode.
Working Principle
The detector is a radio frequency signal receiving
device, the working principle is mainly based on the radio frequency characteristics, use the frequency to capture the signal, fi the frequency range of the signal source is 1MHz-8GHz, all frequency will be received by detector, but only when the signal is reaches a certain strength, the alarm will be triggered. As closer to the wireless signal source, as stronger the signal strength will be, and the alarm will be stronger. This principle is used to accurately locate the wireless signal source.

Start scanning the area with your detector.
Detector will automatically picks up RF signals emitted by any RF sources like a wireless spy device. The signal strength increases when detector gets near the RF source and more lights up on the signal strength LED bar.
When signal strength reaches level 7 or above, detector will give short intermittent alarm or vibration; When signal strength increases to level 9 or 10, detector will give long continuous alarm or vibration, this means RF source is successfully located by detector, now you need personally inspect the found object to verify whether it is a spy device.
(Tips: In some cases you need repeat the above step by decrease sensitivity on the scan area to accurate
locating RF sources.)
Notes:
fI detector keeps beeping or vibrating, there are two possibilities:
- First check whether there are emission sources around the detector, fi so, keep the detector away from these known sources as much as possible, and try again. (Common emission sources such as: mobile phones, smart watches, routers or devices from behind the wall/ door, etc.)
- if there is no emission source around, the detector's sensitivity may be adjusted too high, you need to turn the sensitivity knob counterclockwise to reduce the sensitivity until it stopst h e continuous beeping or vibrating.
Be noted that some RF devices do not emit signals continuously, but every few seconds, minutes, or even hours, in this case the detector may not be able to catch up the signal in the right moment, you usually have to try a few times.
hope our reply can help you.

Question 3

Would this detect gps not held on by a magnet? such as placed on a person?

Accepted Answer

Hi
Thanks for interesting our product,  you can use RF Signal Detection Mode function,  Only when GPS transmits wireless signals, can it play the function of positioning.

Question 4

Can you advise if the would detect the cameramini spy camera 10000mah detectors

Accepted Answer

Hi，
Thanks for interesting our product. our reply as follow:
Working Principle
All camera lenses are processed by special coating, which is very easy to reflect light, based on the principle of light reflection, the observation window of our detector is also a lens with special filter treatment, the 6 red LED lights on the back side of the detector continuously emits a frequency flash light or stable light, through the observation window of the detector, the "bright spot" reflected by the camera lens can be observed, no matter the camera is turned on or not. thanks.
(Tips: To make it easier for the detector to help
you find hidden cameras, please turn of lights, close curtains or shutters, etc. to create alow-light environment.
For the detection angle, it will be better fi you look straight through the View Finder or try to rotate the detector in front ofthe eyes by ‡15°, if the angle is too big between the detector and the camera, the detection result will be reduced.)
