When buying and using a mortgage car, it is best to be equipped with GPS jammers for a certain period of time. Especially the friends who collect the car and buy the mortgaged car from the car dealer, that is to say, once you receive the car, you can open the GPS blocker and put one in the car, and also need one in the trunk! With the blocker on, you can ensure the time for you to pick up the car and return. Worry-free inside. However, the jammer cannot be turned on 24 hours a day, so after arriving at your site safely, you must find a professional person to check the GPS, and at the same time install a GPS positioning device, a dark lock, and change the key.

　　GPS jammers (jammers) can effectively prevent being tracked by GPS satellites, effectively interfere with GPS satellite signals, and protect your whereabouts privacy and information confidentiality.

　　Like mobile phone signals, GPS signals are easily interfered by electronic devices. The signal blocker can block the signals within a certain range, so that all communication devices within the range lose their signals. Installing a GPS locator on the car can make it easy for car owners to find their car on the GPS monitoring platform. However, such a good thing has also been found by criminals. Just buy a signal jammer on Amazon, when stealing a car Open it, there is no signal on the car, and the car is offline on the platform, as if it is missing, no matter how you can find it.

　　It has to be said that GPS jammers also have disadvantages for those who use them. The signal jammer can only be turned on temporarily, and cannot be used forever. As long as he turns off the jammer, the GPS locator will have a signal again. Owners will soon be able to locate stolen vehicles based on location information.

　　In addition to cell phone jammer, one might say they use signal detectors to find GPS locators and destroy them. Yes, this is also true, but this is only useful for some GPS devices. If the GPS tracker is sleeping most of the time, then the signal detector has no way to detect it! Why?

　　For example, some ultra-long standby GPS trackers have only one wake-up time a day. After waking up, the car's positioning information is sent back to the owner's mobile phone platform, and then it enters the dormant state. In the dormant state, it has no signal at all. , car thieves want to detect it, it is absolutely impossible! In addition, it is wireless and free of installation, there is no wiring on the surface of the device, and it can be placed anywhere on the car (as long as it is not placed in a place where the signal is blocked) , which is very stealthy and safe.
