Will a strong Magnet still defeat GPS?

Why?  The Feds tracking you?  You can buy jammers that are really cheap.

keep in mind most of the good jammers draw a lot of power, so if you turn your car off and leave the jammer on you will probably be looking at a dead battery.  If you turn the jammer off when you turn the car off, then the GPS transmitter will function normally.  So in reality, you only have jamming capability while you are actually driving.  

I have not seen any of the brand new devices, but thats been my experience with gps jammers in the past.

That tracker doesn't even closely resemble what is currently being used.

It was found in 2005. I'm sure you could find current models online that the .gov is using without much trouble.

You have no idea how good we can be when we want to use GPS devices. Even in a military/tactical format the technologies are the same to what law enforcement uses

If you suspect your are being tracked, then search your vehicle daily for devices.  When you find one, hire a lawyer.

You're correct about searching your vehicle but you will want to remove it, drive to a truck stop and stick it on a big rig heading out west

One of my targets has done this to me before.  Service manager showed it to him after bringing his car in for an oil change.  It didn't end up on a truck headed west, but he put it on a rental car.

Pretty humorous.

Help me understand this - You are law enforcement officer? You a trying to build a case against a suspected bad guy, so you attach a GPS device to his vehicle to monitor his movements? Really? Does this require a warrant or any kind of approval or can you just attached the GPS device to the vehicle?

If the above is true, I am honestly shocked and amazed!

Yup.  Court Order.  No different than a search warrant.  

There is still a lot of discussion amongst legal folks (and various case law supporting both sides) about warrants, but its the practice of my particular office (and my personal belief) that a warrant should be procured prior to the installation of any tracking device.  

I dont work "homeland security" cases where the line of probable cause to track the movements (or secure search warrants) against citizens for crimes that have not yet been committed is pretty grey.  I work dope cases and probable cause is usually abundantly clear to even the most discerning judges.

A strong magnet will defeat whatever electronic device you have... permanently.

Yeah. If the strong magnet weighs 20 pounds and you use it to smash the electronic device to bits.

If the government is tracking you, it isn't using GPS.   There are many other ways to track someone other than a GPS sensor.  You can use radioactive signatures on a magnet on your vehicle, cell phone triangulation, homing beacons, etc.

I know people hate to think about it, but almost every one of us carries a GPS sensor everywhere we go inside our phones.

And I have seen that be the one clue that broke open a murder case in Cobb. The guys said they were out of town, the phone company said they were around the murder scene. The investigators pushed on one of the guys and he flipped on the others.
