>> Get to know the traditional basics-morse code-semaphore-map reading with compass- AND learn all these skills till you can do any of the tasks whilst seriously injured and in the pitch black darkness-THEN POSSIBLY consider modern technology!!!<<

I don´t fully agree to this. When it´s only for getting the position for SAR, you can benefit from having a GPS without being proficient with traditional methods. If the electronic device fails, you are in the same situation as if you didn´t have it. When it works, you are in a much better situation. And it takes next to no time to learn the basic operation. So IMO it doesn´t hurt to have modern technology as long as you are aware of the fact that you can´t always rely on them. It would be advisable to learn the traditional skills though. That would significantly enhance the odds if the modern devices fail.
