Find covert devices
Bought this for a friend who had privacy concerns and rightly so. Tracker discovered on IPHONE even when switched off it was still transmitting their location. Note, when checking your car turn the engine off. All cars have GPS, wi-fi etc and it will give a false positive if the engine is switched on. The engine must be switched off when sweeping the car for devices.

Inefficient device
Quite easy to use but not sure if it works as it beeps everywhere, even where there is nothing (no electronics). Tried it in the car too but the same disappointment. The description says it can detect extra microphones in the phone, but doesn't seem to work, and yes the phone was turned off. A waste of money...

Easy to use and accurate!
One of the best tools to have been invented and in my home. This detector is so easy to use and very accurate! Well made! Our home use to be rented out to many different and unknown to me tenants before we bought it so I bought this to make sure there weren’t any hidden cameras planted. We like to travel and stay at nice Airbnb’s so I can’t wait to take this on our next trip. Everyone should have one of these, I’m still disappointed that it took me so long to purchase one.

Gadget inutile
ne fonctionne pas (se mets à capter des signaux dans le vide, malgré le réglage de la densité)et je trouve dommage de pas avoir de notice en Français (obligé de fouiller sur internet). Gadget inutile !

Good 3-mode detector. Easy to set-up and easy to use (no technical knowledge needed)
It really works. The user should follow instructions in the booklet that it comes with the detector to set-up the detector. Very easy to set-up. No need of professional knowledge. I tried it for RF detection mode and Camera Finder mode. I have hidden cameras in my house along with my alarm system and it found them. I did not try it for GPS Tracker detector (Magnetic Field Mode) yet. Overall, excellent Price/Quality.

Sensor Sensibilität lässt sich schwer einstellen. Anleitung ist etwas umständlich. Preis-Leistungsverhältnis geht.
