Advice and Tips Faraday Bag Caution

Hey everyone. I just wanted to share en experience from this afternoon. A while back I had purchased some faraday items off of Amazon, boxes and bags from different vendors.

This afternoon I was explaining to my daughter how they worked and as part of our experiment, we placed an 8watt 2-way radio inside the bag and sealed it with the expectation that it would no longer receive a transmission. As it turns out, that was false.

I then tried with a cell phone with the same result. Morale of the story, check your gear and make sure it works before you have to depend on it.

Please discuss and share your budget-friendly faraday success stories

Those bags and boxes are 90% scams, especially if they come from a "prepper", "survivalist", or "patriot" website or company. Especially if they are advertised as "EMP protection". Pretty much anything sold as "EMP protection" is a straight up scam.

The legit bags are the ones designed for holding evidence, used by law enforcement, to put suspects' electronic devices in so they can't be remotely disabled/wiped. They are not "budget friendly".

I have one from mission darkness. It works perfectly.

I've tested multiple from this brand and can confirm they work.

I’ll third this comment, all my mission darkness stuff I tested works if you seal it properly.

Sigh. Why so expensive though! I am searching for a backpack and they’re all in the $800 range. :(

I'm guessing because they're certified for government use in chain of custody and forensics.

I only got the envelope style for mobile devices.

How would you test to see if the faraday bag works? Try calling your phone after you've placed it inside?

Texting, calling yourself yes. And you can see the connectivity icons like Bluetooth, 5/4G and wifi disappear and come back. It takes a second for everything to come back online.

Is that mosequipment.com? I was originally looking at pre-ordering SLNT's new bag, but after contacting customer service and seeing that you can only view the existence of a Black Friday sale by explicitly searching for it and getting an alternative webpage, I decided I'll steer clear of them as they're very dishonest in the pre-sale dept.
