## Description

Product Description K20 Product Description

Review: 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.
Review: Impressive - Lovely looking packaging with a good quality feel to the product. Very user friendly and extremely accurate

## Questions & Answers

**Q: Why doesn't the detector alert when I know a tracking device is nearby?**
A: Some tracking devices do not continuously transmit wireless signals. Certain devices may remain in standby mode or only transmit data at scheduled intervals. For best results,use both RF Detection and Magnetic Detection when performing an inspection.

**Q: What is the difference between RF Detection and Magnetic Detection?**
A: RF Detection Mode identifies active wireless transmissions from electronic devices. Magnetic Detection Mode helps locate magnetic objects attached to vehicles, bags, Using both modes together provides a more comprehensive inspection process.

**Q: Why does the device alert near metal or magnetic objects In Magnetic Detection?**
A: the device is designed to respond to magnetic materials. Many everyday objects contain magnets or magnetic components.When an alert occurs, inspect the detected object carefully to determine whether it is a normal magnetic item or a suspicious device

**Q: How should I adjust the sensitivity for accurate detection? Detection environments vary significantly.**
A: Before scanning, gradually reduce the sensitivity until the signal indicator remains stable and the device is no longer continuously alarming. Then begin scanning slowly to help identify the source more accurately.

**Q: Where can I learn how to use the product correctly?**
A: Please refer to the user manual and operation videos available on the product page. We also provide troubleshooting guides and demonstration videos to help users understand product functions and recommended operating procedures.
