If possible, the individual examining the site should carry adequate maps, a compass, a drawing pad or board for making sketch maps or tracings, and a metallic measuring line. (A wire knotted at regular intervals is adequate for measuring. Personnel should not use twine or cloth measuring tapes because stretching or shrinking will make them inaccurate if they get wet.) If the observer can carry it securely, he should also carry a probe rod for probing prospective burial sites. D-17.
