If you have never known a GPS signal jammer before, it is especially important to pay attention to the signal that the GPS jamming device cut off while purchasing. GPS signal jammers are mainly used to shield their position and protect their location privacy. It can perfectly block the GPS signals and the transmission of GPS signals, so other GPS trackers can't detect and track your location.
Different types of gps signal jamming devices have different price/interference frequency bands and shielding ranges, so pay special attention to the signal frequency bands and other technical features shielded by each interferometer before purchasing. The GPS jammers currently on the market are mainly portable GPS interference instruments, and are equipped with a car charger, with interference distances between 5 and 100 feet.
In addition, gps signal jammer can be designed differently, so you can choose from portable or handheld gps jammers and desktop benchtop jammers. If you're sure to use it in one place, you can use a desktop gps jammer, a portable gps jammer that's popular because it's easy to carry and cheap.
