Of course, there are many different types of GPS jammers. If you want to spend a lot of money on one of these devices, you can be absolutely sure that you will have the opportunity to shield any signal over a wide range. Of course, if your budget is tight and you don't think you can buy expensive equipment, you can buy one of these low-power devices. Their scope of work is very decent, especially when their main goal is to stop people in the surrounding area. I think their distance is 5 meters. This is enough, especially if you are on a bus and want people to shut up for a minute or two. Such a team will definitely help you.
There are many types of GPS blockers: some block only one frequency, while others block all three frequencies simultaneously. Of course, there are many high-end models that can block almost any tracking frequency (3 x GPS, GLONASS, Galileo, Compass, etc.), and they are the best choice if you want to be completely sure that you are not being followed. However, these devices can also be very expensive, so you must determine how much you are willing to spend on one of these gadgets. I assure you that if you decide to spend more money on gps jammer, this is not wrong: this transaction is worth every penny and is the best way to ensure that it will not be tracked remotely.
Thanks to the civil modification of the military blockade and the development of the entire technology, it is good to know that the authorities are doing everything possible to protect the innocent.

All these gps blocking devices are one step ahead of terrorists.
