Why Do I Need EMP Shield?

  • The Government has released an EMP Executive order & Homeland Security is urging people to get prepared quickly!
  • Although the grid may be down, your electrical equipment and home will still be functional if you have EMP Shield. 
  • EMP Shield will ensure your vehicle operates after an EMP helping you get home, save family members, or even get supplies while others cannot.
  • Your home will be 100% protected from lightning saving you thousands of dollars and months of time if you are hit with lightning.
  • If you have a solar system or generator, you will have power and functional equipment while others do not!

How Has This Been Tested?

Isn’t a nuclear explosion required to create an EMP?

The threat of an EMP is the large amount of electricity that is induced into conductors that generate heat and can be destroyed.  There are only a few testing facilities in the world capable of producing the same amount of electricity that an EMP produces. 


EMP Shield has been rigorously tested at the Keystone compliance facility which is a federally approved testing facility that is used to conduct many of today's most advanced and rigorous technological tests. Out testing and evaluations conducted at the facility were documented in depth to show the true ability and durability of the EMP Shield. Below you will find the complete Keystone Compliance testing results of the EMP Shield.

How Does EMP Shield Work?

EMP Shield will protect all the electronics and equipment connected to your electrical system.

This is accomplished by shunting (shorting) the over voltage coming in from the grid and the induced voltage that is collected within your home.

Whether the source of electrons are from within your home or coming into your electrical system from outside the home (the grid), the Shield will see the surge and protect your electrical system. Our technology reacts in less than 1 billionth of a second. Since the shunting is completed incredibly fast, the over voltage is drained away from the equipment before the voltage can rise high enough to damage any equipment. We call this new technology SightSpeed™

    Have EMP Shield for my home and cars just ordered one for a family member. I talked a friend into getting one for his home and car several months ago after he had a power serge that took out his refrigerator and washer. My friend called me this weekend said he just had a surge and the shield tripped and did its job. He said he was skeptical when he bought it but now he’s a happy camper.
