Expanding on previous post a bit, if you're thinking you might need solo emergency comms you're committed to like 10 million other things now. Comms alone... what happens if the inreach is lost/broken? What happens if you have to hike out? What happens if I cant get a signal? What happens if the other person gets separated somehow? Etc.
So now you're thinking you know ham license, knowledge of antennas, repeaters and so forth, list of repeaters, cab ham radio, handheld radios, and at least one Inreach.
Then extrapolate what's involved with comms to recovery, mechanical, medical, weather, having to hike out, etc... it's probably years of research, gear, prep to go remote solo like this responsibly. Lots of little details and layers of redundancy like can you read a map and compass when your all your tech is burning up in a vehicle fire and all you have now is your grab bags? Can you filter water? Can you stay warm? Can your glock 20 kill a Grizzly? Sorry I get a little OCD on doomer scenarios it's too fun

ok I'll skip the part where you're dealing with a sucking chest wound from a gun fight with narcos after accidentally overlanding in to their herion poppy grow op and have 3 grizzly bears on your blood trail
