With the increasing use of GPS - and the increasing likelihood of its invasion of privacy - many people are turning to GPS jammer to protect their privacy. For some people, blocking GPS signals and protecting privacy are especially important. Vehicle tracker blocker is an important device to protect personal privacy.
The frequency of the radio signal transmitted by the vehicle blocker is the same as the frequency of the satellite signal. Since the GPS satellite signal is weak, a GPS scrambler that emits about 2 watts is enough to destroy a GPS signal of about 10 feet. This makes it impossible for the in-vehicle system to determine its location and report to the GPS location center registered with the vehicle.Jammer-mart sale gps blockers at cheaper price.
