Consider adding a roll of survey tape.
Many times a search will get within 15-20ft. of a victim and still miss them.
If an emergency happens teach the scout to tie one end of the survey tape
to a rock, branch or any fixed point and then string out the complete roll
and tie it to there belt or in camp. The tape should be strung across a terrain feature, ie across a trail, in a straight line up a hill, perpendicular
to the creek bed, drainage etc. A searcher Will at some point cross the
tape and find the victim.
