EMP Cover EMP Bag Kit - Jumbo 21"x24" Two Pack: 80x More Faraday Cage Shielding for Electronics
Package ContentsTwo pack of 21 inch wide x 24 inch tall EMP Cover shielding bags.  (Note: size is internal, usable space.)Includes special closure to help keep the bag well sealed. The closed bag creates a secure Faraday cage environment to shield against EMP energy.Also includes desiccant bags to remove moisture inside your sealed bags, protecting your stored electronics.Not all silver bags are the same.Tests at NASA show up to 49 dB of protection, with an average of 45 dB protection. That is 10 times more protection than required by the highest  military specification (MIL-PRF-81705 Type I). Bags that just meet the military standard only provide 1/10th the protection you need. That is why EMP CoverTM shielding bags are "Beyond Mil-Spec."Even worse, some vendors sell regular anti-static bags as EMP protection. Regular anti-static bags create a very weak Faraday cage, only 1/80th of what you need.EMP Cover Bags Protect Against Strong EMP AttacksTo protect against an EMP attack, you need 45 dB of shielding. That amount of shielding will protect against a high-altitude blast created using the largest warheads. (See our site's EMP simulator for more details.)Extra ValueBeyond EMP, your backup electronics need to be protected against dust, rain, dirt, oils, and other nastiness you may encounter.EMP Cover bags deliver, giving you water and oil resistance in a strong and lightweight material. Each bag weighs only ounces, but has a 40 lbs. tensile strength and > 20 lbs. of puncture resistance. They are a great way to store backup electronics in a ready-bag or in your vehicles.NOTE for Cell Phones: This material is not intended to keep your cell phone hidden from tracking or hacking. It will block most cell phone signals, but not if you are in the path of a high-power directional signal. To block your cell phone from tracking, search Amazon for our "HideCell" product line.
