    All transmissions can be traced. Cell towers can be used for location targeting. Triangulation is an accurate method of location.

    Seems to cost a lot and the sales pitch is buy now as prices will soon go up. I never buy anything is sales pressure is too high.

    I have nice Family service, CB, Ham radios so not interested .

    Perhaps for a young person without any radios who uses a smart phone would find it useful.

    seen this same thing pop up on a FB prepper page, I mentioned the same thing that it could be traced. Had some jack ask me and how do you trace it? my response was quit simple, if it emits a signal, it can be traced! then the flaming started. Needless to say, the post got deleted, and no more mention of it. If it is a SHTF scenario, no means to replenish the charge on the battery, it is very useless item. If you need to survive in a bug out, off the grid local you need less tech, and more ingenuity!!!!! Old military field phones or sound powered phones would be better if you got OP's preset. And if your bugging out to a deep wilderness local, why bring a signal emitting comms device if you don't want to be found?

    We went with the Midland FRS radios with rechargeable batteries. We have several ways of charging the batteries.
    Maybe not the best choice but an easy choice and they seem to be durable and work ok through 3 miles of woods with a little bit of hills.
