It might be useful to have a few walkies stored in a box/faraday cage.None, if SHTF involves an EMP then all comms will be unusable.

What's your thoughts on this...Incorrect
I don't know how many times I have addressed this assertion (that EMP will destroy all electronics), but it has been enough times that I shouldn't have to do it again. *sigh*
But here goes:
1) EMP is line of sight. If your electronics are behind a hill/mountain, in a valley/gulley/ravine, such that the EMP point source is not directly in a line of sight, then your electronics are less vulnerable to the EMP.
2) A lot of electronics are internally shielded to reduce/prevent RFI. If an electronic item is inside something, like a metal building or a car, or a case, that metal may provide enough shielding to reduce the impact of the EMP - possibly enough to where the item can work in some fashion. If you store the item in a container that would serve as a "Faraday cage" it will be less vulnerable to EMP - it isn't hard or expensive to make such a container.
3) Some electronics are more robust than others when it comes to something like EMP. Some electronics might be temporarily disabled by EMP, such that if you turn them off and turn them back on, they will reset and start working again. Some will show no impact at all. Some may not work correctly but still work somewhat.
4) Some electronics might be less susceptible to EMP damage if they are not turned on at the moment of the EMP. Something that uses an antenna, like a transceiver, will be less vulnerable to EMP if it is turned off and the antenna removed.
In short - it depends on the circumstances. It is not correct to assume that all electronics will be kaput if there is an EMP/CME.

If there is fallout (nuclear or volcano), or other threats/risks (say it is dark and there are strangers wandering around outside), it would be beneficial to have a means of wireless or wired communication that doesn't require you to be outside your shelter.As it is, I'm not too involved with the "outside world". If I need to talk with my neighbors I just walk over and talk to them.
The website is all flash and no facts. I'd want to read what the report they tout has to say about them - if it were positive they would show it to you. I'm in full agreement with @The Heretic that it's a gimmickWhat's your thoughts on this...

It's been a while since I evaluated these so I went back to the first link I posted. There is really a lot going on with these phones to provide security when used in "walkie talkie" mode as opposed to cellular.Most cell phones use some form of Spread Spectrum, which, depending on the type, is either frequency hopping or time domain (TDMA) or frequency hopping via code division (CDMA). There are a lot of transceivers that use FHSS - e.g., Bluetooth and some unlicensed walkie talkies.
Granted, these are not "security features" - they are used to share frequencies.
I don't know how a device like that could prevent an EMP or Carrington Event from affecting the wiring of a house or car. I could be wrong, but it seems that the only thing such a device could do is work as a circuit breaker, or surge-protector.
Pretty much this ^ the best it could do is protect from a surge on incoming lines (as I think I mentioned). Other than that (if it could do that - I wouldn't bet on it), it would not protect electronics from EMP induced voltage/amperage in the electronics themselves. Only some kind of physical non-electronic shielding can do that.I don't know how a device like that could prevent an EMP or Carrington Event from affecting the wiring of a house or car.

Shunting, if it was fast enough (and I doubt it would be), would accomplish this. I also doubt the device could do what it claims. And as I said, even if it did, it wouldn't protect devices from EMP induced directly to the device.I don't understand how an electrical pulse can be "drained away" by this device - but electricity is not my area of expertise. I would think that having several grounding rods attached to a building's wiring would give the charge somewhere to go. Maybe someone here can school me about this.
So a 12ga then? Who ya gonna call?If there is fallout (nuclear or volcano), or other threats/risks (say it is dark and there are strangers wandering around outside), it would be beneficial to have a means of wireless or wired communication that doesn't require you to be outside your shelter.
There are now cell phone scanners that can be used to at the very least detect cell phones even though some (CDMA) freq hop. Same with DMR/etc.It's been a while since I evaluated these so I went back to the first link I posted.

..."There is a BIG technology difference between the iDen/ISM units and the FRS Units, in that the FRS units are just FM TwoWay Analog Radios, that can be picked up on ANY UHF Scanner and listened to, whereas the iDen/ISM Units are TOTALLY Digital in nature, because they are first, and foremost, Digital Cellphones, and when using the ISM Band, they use the same Hardware, for transmitting, and receiving. This means that ONLY a Digital Receiver, (Very High-end, and Expensive) programmed for the specific Frequency and Spreading Code, will be able to receive these signals. The design of these units allows for ISM Band to be divided into 10 chunks, or channels. Then the audio is digitized, and added to the selected Spreading Code, that then spreads the resulting RF, over the entire Channel Frequency chunk, making it very hard to even see on a Spectrum Analyzer. This is the instrument that Big Brother uses to find Comms, of Bad Guys, in the field. What we have here, then, is effectively, a cheap, small, portable, Comms device that uses Spread Spectrum Technology, to stay hidden, while in operation, from the normal snooping, and scanning, technology used by of 99% of the world. There is another feature of these Units, that for Private, Secure, Unit to Unit Comms, there is a PDN Code, (Ten Numerical Digits) that each unit has programmed in, that can be used, instead of the the regular Spreading Code. When in this mode, only these two units can hear, and communicate, with each other, because no other units will have the same PDN Code. Therefore it makes for a VERY Secure Comms System for CN AoO comms. This is as good of Comms Security that one can get, in the civilian world, without spending thousands of FRNs per unit." ...
I put one on my 4x4 pickup truck and it is simple to install if there is room around you battery somewhere. For myself I had to pull the battery out but there was room to mount the EMP Shield next to the battery. I used the incluced velcro and also two long sheet metal screws. It also protects against solar flares as well if another Carrington Event happens.What's your thoughts on this...

If you have a key FOB or an alarm remote on you car key ring you need to protect with a EMP proof bag as well.I put one on my 4x4 pickup truck and it is simple to install if there is room around you battery somewhere.

But I would not want to be driving if an EMP event happens since most of the cars and trucks will be dead on the road and working pickup is very bad news for me. They also have a new smaller design called the EMP micro shield which is a a bit smaller which would be good for cars and trucks that do not have have a lot of open space in their engine compartment.

I don't have any experience with any other products from EMP Shield. I would like to get a Home unit but hire an electrician since my circuit breaker box has 220v breakers at the top but watching the installation video for the home unit you need 20amp breakers at the top.
