SHEILDSAK takes you off the grid

SHIELDSAK

SHIELDSAK

Shooting, like the rest of everyday life, is becoming more and more technological every day. And nearly everyone, including shooters, carries a phone or tablet with them wherever they go. The advantages of these technologies are obvious, but they don’t come without concerns. Gun owners, often even more sensitive to security and privacy concerns than most, will want to take a look at the SHIELDSAK by the makers of the waterproof, touch-capable LOKSAK.

Woven from seven types of metal in a ripstop bag, the SHIELDSAK is a Faraday cage that blocks all signals in and out. A cell phone with an active signal will disappear off the grid in 5-10 seconds after being sealing in a SHIELDSAK. Gone. It won’t ring. It can’t be tracked. And the user will regain a little autonomy. Items with RFID chips such as passports, ID cards, or credit cards disappear instantaneously and can’t be scanned.

A new coating has upped the durability of the SHIELDSAK to 5-7 years or longer if treated well. The smaller one (pictured) runs $65 to $69. The larger size for tablets goes for $149.

    Can I get a hat made of this stuff?

    • Maxcoseti

      Pure genius sir

      • gunslinger

        it won’t work.
        only tin foil

        • José Pulido

          All of the tin in North America “ran out” in the 20th century, sorry.

          • gunslinger

            foil sheets are commonly referred to as “tin foil”

            just a habbit. just like a sugary carbonated drink in the south is a coke, even though it may be a pepsi, root beer or any other assorted beverage!

          • M.M.D.C.

            Yep. Somehow “aluminum foil hat” just doesn’t have the same ring.

          • gunslinger

            unless you say it with a British accent and pronunciation

          • avconsumer2

            AL-YOU-MIN-EE-YUM!! (actually, I believe that’s the ‘strailian vernacular)

          • Danmaku

            Well, the Australians are the British rejects so to speak ;P , so I wouldn’t doubt the speech crosses over in several areas.

  • disqus_BFYtgm77gn

    Wouldn’t turning off the phone do the same thing?

    • Michael

      No, A phone can still be tracked. It can be turned back on, and they can listen to you and watch you even if you have turned it off.
      Why do you think they were so quick to get the cell towers back up in Iraq

      • JumpIf NotZero

        Stop watching CSI.

        You’re 100% wrong.

        • Asdf
        • BOB

          you need to pay more attention to the news, Michael is 100% correct.

        • BuzzKillington

          No, he’s not. A phone is still able to be tracked while in airplane mode or turned off, with the main device that PD’s and LEA’s are using.

        • grayjohn

          The FBI just admitted they can do exactly what Michael said.

  • motzus

    Turning off the phone may not do the same thing. Depending on the phone even when it is “off” the radios etc. may still be active and traceable.

    But I’m not sure why you need something this expensive. You can buy anti-static bags which accomplish the same thing for 10 cents. If you build your own computers you probably have a bunch lying around. All the cards for your computers came in those bags.

    • ArmyCop119

      So do PopTarts.

  • Nick

    If you don’t own an iFail you can yank the battery, now that’s untraceable.

    • flyingburgers

      Take apart pretty much any phone, smart or dumb, that has a removable battery and you’ll find that it has a small rechargeable lithium cell inside.

      • Nick

        Yea, but iPhones are nearly impossible to open. (Samsung phones you just pop off the back cover)

  • The Nev

    Well… I keep pushing my money into the screen but nothing happens. How do I acquire this, guys?

    • JumpIf NotZero

      Well, if you’re the type of sucker that pays $65 for a tin foil baggie…. I’ll sell you a few right now!

  • Adrian A

    It’s called the Power Off Button

    • The Nev

      Doesn’t work that way. A phone that is off can still be tracked.

      • Adrian A

        Not True. The batteries are no longer powering anything when the phone is off.

        • dirt

          Depends on the phone. Many phones these days even include features where they automatically turn on at a time you set or when you have an incoming call. To be sure that it’s truly off, you have to remove the battery.

        • BOB

          you ever hear of a ‘backdoor’? It’s built into pretty much all GUIs and OSs out there now.

        • The Nev

          So those multiple news outlets that came out a few months ago and said the FBI and others can turn on your phone and activate the camera and mic were just lying? Whew, thanks anonymous internet truth-teller.

        • theUglyTruth

          Not true, the police track ‘turned off’ cell phones all the time, common in murder/missing persons cases. Doesn’t completely shut it off unless you remove the battery

        • micko77

          Galesburg, IL police tracked a stolen phone in December of last year… a stolen Iphone that the thief thought was safe in the “off” mode, yet the newspaper stated that it had been found by the cellphone company. It had been stolen from the corpse of a railroad track suicide. But don’t worry, just turn it off, all will be just fine.

      • JumpIf NotZero

        You guys watch too much garbage TV.

        Even for Andriod and iPhones with non-removable batteries, the radio is COMPLETELY OFF. This secret transmission scheme you’ve imagined (I’m and EE, I’d know) would be completely against all FCC, FAA, and entirely unacceptable to some governments (Germany for instance with strict laws regarding OFF and Standby states).

        • flyingburgers

          That doesn’t protect against somebody intentionally modifying the phone, say with a second battery, in order to conduct espionage.

          In any sort of area with security, they leave make you leave the phone outside, not only for this but for the possibility that you’re recording.

          If you’re an EE, you should know about the origins of RFID: the Soviet Thing, a passive RF listening device.

          • JumpIf NotZero

            Congrats, you’re in the running along with Lance for Most Facepalming Comment on TFB.

          • Asdf

            Total BS. How does a phone know what time it is if it is shut of. Try it. Go someplace without signal, turn if your phone, wait 10 minutes, turn your phone back on and the clock will still be correct.

            Just because it is “off” does not mean things aren’t running off the battery.

          • JumpIf NotZero

            It’s like arguing with 5year olds. Yes, there is a tiny battery (or super capacitor in new designs) that draws enough to keep a clock running for the RTOS. There is NOT a chance of your phone powering up the radio chipset (which i have directly worked with on embedded hardware designs) while OFF, it could be done but it isn’t on consumer released products.

            But sure, buy a $65 tinfoil bag. I really think you should.

          • Asdf

            Hey cool. I am in embedded design as well and you are still full of BS. Phones can possible be remotely turned on in their so called “off state”.

          • The Nev

            Nice try, NSA shill. We’re not going to fall for your disinformation.

          • Aurek Besh

            The way phones have been designed the past decade, they don’t have enough room for a proper primary battery, let alone a secondary. 🙂

        • FourString

          Garbage TV includes the Bourne Supremacy and Ultimatum? Wha? o_O? *scratches head*

        • DarkHuntress

          Ever hear of the NSA?

        • DougE

          Since when does .gov follow it’s own laws? Datamining was used before 9/11 and actually picked up intel on what the attacks, but it was decided they wouldn’t tell the FBI because they knew what they were doing was illegal. Congress is frequently exempting themselves from laws they pass. They don’t care, they just want power, knowledge is power, your cellphone contains and can provide realtime knowledge.

        • NikonMikon

          So how much are they paying you to shill? Link posted earlier disproving you completely: http://news.cnet.com/2100-1029-6140191.html

          BTW throwing around EE like that…. lol.

          • JumpIf NotZero

            Do keep posting a link that is entirely misleading. The phones in that article were actually modified and planted.

            Keep shoveling.

  • Clint Notestine

    aluminum foil works too and is a hell of a lot cheaper plus when you realize you look like an asshole you can use it to wrap your sandwich.

  • Nathaniel

    …what’s a “sheild”?

    • Asdf

      I before e except after shut up.

  • AmmoralDeviant

    But does it also protect said devices from EMPs?

    • phuzz

      Depends how big the EMP is. If you’ve got the phone in your pocket then I’d guess you’d be in danger before the phone got fried.

  • karm42yn

    Get a zip lock bag, adhesive copper tape and 5 minutes of free time. There. Of course I can understand that it won’t be as durable but still a hundred times cheaper. Or you can get a tiny pelican case and put tape all around inside.

    • Asdf

      Yeah, but chances are you will cut the living crap out of your fingers if you do that.

      • karm42yn

        Not at all. They sell copper tape in every garden store for pennies. It may be thin but it’s still based on plastic and the copper layer is extremely thin so no worries.

  • John Dalton

    AH HA!!! I am going to buy a pair of pants made from this stuff so the aliens will stop tracking me with the device they inserted with that probe!!!

  • Edward Franklin

    Seems like the product for someone who doesn’t want to build their own out of tin foil and some tape. Less scrupulous people have been doing that for years to steal tagged products from department stores.

    I will these look a lot better and probably have a nice lining so they don’t scratch your screen or anything else so they do have their place.

  • Panzercat

    And my guess is you just shortened the endurance of your cellphone considerably as it tries to increase the signal strength in order to punch out to the nearest tower while continually failing to do so from within the bag. Battery life will get ugly, fast.

    But if your battery is the permanent rechargeable type, I guess that’s you’re only option.

    • avconsumer2

      I imagine one would turn their phone off when utilizing this device.

    • iksnilol

      Activate “flight mode” it stops it from reaching after a signal.

  • Edgar

    Time to ditch crappy computer running every ones life. If you want to spend a few hours a day/ and or night reading news blogs or sits fine but stop letting it run you at work driving and on the range come on.

    • Cymond

      I agree in many ways. My wife’s eyes are essentially always glued to a screen, even at dinner. However, even those of us who are not completely addicted do often keep the devices nearby. I rarely use the phone yet I never step out the door without my cell in case she needs to contact me.

  • gunslinger

    needs more tony siragusa

  • Yazz D. Atlas

    Taking the battery out is recommended if you do not want to be tracked or spied on.

    A one solution to subvert digital tracking is to have a different physical phone and some pre paid SIM cards. You don’t store these at your house and buy them with cash or through a proxy. Once you have them ask a friend to hide it at there house or maybe bury an ammo can somewhere along a path you walk the dog. Leave you primary phone at home and then go use your hidden phone. As long as you don’t connect with the any of the same people on both phones it would be difficult to track and connect the dots.

    This is overkill for most people and if your that paranoid you should rethink about having a cellphone.

    If you want some good info about Prism and some tools being used by the NSA you should watch both of these Youtube videos.

    “Through a PRISM, Darkly Everything we know about NSA spying” (Over view of what is known)

    “To Protect And Infect, Part 2 The militarization of the Internet” ( Tools discovered in the Snowden files released.)

    If you haven’t read or viewed enough already. There is an good article called “NSA uses covert radio transmissions to monitor thousands of bugged computers” on http://arstechnica.com/ with links to other sources.

    • NikonMikon

      You deserve so many more upvotes than you have.

      • ATman

        As anyone out there put out the possible theory that who gives a rat’s @#$& about the CSS/NSA/CIA/FBI/Homeland/My mother wanting to watch me while I shoot a Ruger 10/22 in 30 Km/hr winds. A point of interest is that current satellite technology allows them to read the SN from my gun from space so if they are looking for me I’ll be at the range on the worst day possible as I work retail and only get a day of once every 8 days. They can find me honing my 55yrd shooting skills. On another note answering phone calls with gunfire in the background is fun especially when telemarketers are involved. Also a 5$ ammo can or a 1$ lunchbox or 1$ duct-tape/ 1$ aluminum Foil/ 2$ Velcro would achieve the same effect without the sticker shock. Don’t get me wrong the design is cool but the price is $60-$135 over priced.

  • GuidoFL

    Aluminum foil also works ………

  • Verner

    This may be useful for industrial counter-intel. Also, as a tax advisor, I’ve had many clients demanding me to take the battery out the phone. If I had this, I wouldn’t need to disassemble the damn thing every time a more paranoid client shows up. Qestion is, will it availible in europe, and if yes, when?

  • Tex

    First off, YES some phones have low-level operations still going on even when ‘powered off’. While the ‘radio’ may not be powered up all the time, it may still ping the network, record/report location data, etc. Even if it is not actively transmitting anything, it can passively monitor which networks are in range and store this info, giving a pretty good idea of location. And much of this info is/can be reported (supposedly ‘anonymized’) to the carrier or OS provider to ‘improve services’. This is not tin hat conspiracy territory, these are facts that have been quietly disclosed by the manufacturers and covered in major legit news venues. As for those saying they can do the same thing this ‘Shieldsak’ CLAIMS to do with some aluminum foil or copper tape, you may be giving yourself a false sense of security. While I have no idea of how well this device functions as a Faraday cage (I have not tested one and it may be complete and total garbage) I CAN say that you are unlikely to create a satisfactory shield out of foil or tape. At my current position I work closely with our company’s EMI test lab. We make electronics products for space and defense uses, many of them hardened. While this is far from my area of expertise, I have ‘talked shop’ with those boys over lunch and in dept. meetings to know that there is much more to shielding than wrapping something in a layer of conductive material. Depending on the material and the wavelength of the energy you are trying to shield, a tiny pinhole or gap of a few microns can be enough to allow energy through. Sometimes even complete continuous solid shielding is not enough if it is the wrong thickness or wrong conductivity etc. Again, this Shieldsak could be complete junk too, but if you’re driving to meet your underground cell to plan a gov’t overthrow, I wouldn’t trust wrapping your phone in Al foil or copper tape or any of that.

    • JumpIf NotZero

      I can tell you positively that no modern phone is “pinging the network” while off, the radio chipset it literally underpowered by the system basis chip. I work with the sbcs that all the latest arm powered phones are using. They keep the clock alive, and ask the CPU to power up when it’s time to do so.

      It’s not impossible to power up the CPU silently, check in, do its work and shut down. ON A MODIFIED DEVICE. But this does not happen on consumer products.

      Let me just explain it this way….. If you put an iPhone in Airplane mode… And it transmitted ANYTHING on ANY spectrum for ANY reason…. IT WOULD BE ALL OVER THE INTERNET.

      Where is it? I see a LOT of speculation from Shieldpak Hatters, I see one chesseball article from 2006 that is actually discussing a modified phone on an extint network… Where is the rage again?

      • Tex

        So the release from Google a year or so back that acknowledged that even with location reporting disabled, android devices were storing/transmitting location data, and that even when ‘powered off’, it was monitoring/logging strength of nearby networks, which were later transmitted to google (anonymized of course) they were just making this up? I trust reports from major networks which include official releases from Google, more than some guy who works with character systems for RISC processors.

  • WildBillB

    go into the local computer store or your favorite geek – the anti-static bags for all electrical components are thrown away daily.

    best option? pull out the battery when not in use.

  • bmartin79

    I want a wallet and a cell phone holder that does this . It will let me use my cell phone when I feel fit as well as not have to worry about someone stealing my info on my bank cards .

  • marineh2ominer

    I just keep mine wrapped in aluminum foil , I think a piece of a space blanket would work just as well .

  • Cymond

    I’m confused. Why would I want to put my phone in a bag where I can’t use it, that will drain the battery as it struggles to find a signal? It would be much cheaper to just take the battery out when I want to go off-grid, plus it would save the battery charge instead of draining it. The only reason to use a bag like this is for something like an iPad that Apple intentionally made it impossible for the user to remove the battery.

    • gunslinger

      aparently, w/o the battery you can still be tracked. best use would then be to put the device in an “off mode” so it’s not searching for a signal, and won’t be used to track you when you aren’t “aware” you could be tracked. obviously if you make a call, send a text, surf the web… then sure.

  • Fox218

    I work with law enforcement at the local level (no feds). I’ve had the opportunity to “ping” some cell phones and its not always guaranteed to be accurate. Usually when I receive a response it goes something like this, some percentage of accuracy I have had responses as low as 0%, 70% and as high as 90% never a 100%. Proximity to cell towers is the normal response 100 meters 200 meters I had ATT give me a radius of 2 miles ( not very helpful) once. Even with GPS coordinates it can be finicky I had a set that put the subject in the middle of a lake which was verified as wrong when he was picked up down the road by a deputy. If you have sprint and someone tries to locate you good luck there is a 6 hour delay in sprints gps data. I had a lady get beaten and dumped in the woods and couldn’t provide a location so she could receive medical attention I contacted Sprint and they advised it would be 6 hours until they would have updated information. Like I said I’m operating at the state and local level so I’m not familiar with federal level equipment or techniques.

  • gerry

    does this block gps from tracking you?

  • Gerry

    does this block gps signal??

  • John Daniels

    Now 5.11 and other companies should offer pants with this material used for the inside pouches of it’s pockets. It’s a step in the right direction, but people are still going to want to just toss a phone into a pocket, instead of stopping to put it in a bag first.
