I can see with a group that intends to scatter why you carry the radios and besides, that is your thing. Nothing wrong with that. I got into the outdoors before any of these goodies were available, so I am comfortable carrying none of them, but I have used a GPS for nearly twenty years (at first, a professional application) and my wife has dragged me, kicking and screaming, into the twenty-first century, so I regularly ( usually -well a lot of the time) carry a cell phone. I have been impressed with the coverage I have experienced, even in fringe areas.

As these gadgets get smaller and lighter, I will be open to including more of them on my outings.

None of these diminish the need to carry some variation of the classic Ten Essentials, including FAK and other critical items. Circumstances may be such that a timely intervention by SAR is not going to happen. You, yourself, are the best source of immediate emergency aid.
