Some good advice here. Thanks
Can I also suggest that you take a few precautions if you do get "lost". For example, a whistle or small mirror will help if you are with people and do not take up much room and are not weighty. A space blanket if you are out after dark in winter. If not with people then tell someone where you'll be and when you will be back and what to do if not back (although this is not going to be a saving point if you get lost on day one of a 10 day trip). Water is essential. A sat phone certainly handy and/or UHF radio. And spare batteries. These last items though start adding weight and complexity to things.
