D When accurate measurement is necessary, as in grid searches or plotting trails, and no GPS is available, pacing is the most practical method available. Measuring distance accurately by pacing requires experience. Every person has a different pace length and the size of their step will vary depending on speed and the type of ground they are traveling on.
95 DISTANCE MEASUREMENT Pacing (cont.) IN THE FIELD To obtain pace information, measure out 100 meters and count the number of paces required to walk this distance. Repeat the route until the number of paces becomes consistent. Try this exercise in a variety of locations as pacing changes depending on the terrain.
96 DISTANCE MEASUREMENT String Boxes IN THE FIELD A string box is a plastic belt case containing a spool of thin string and a measuring device which registers as the string is let out. The user simply ties the string at the starting point and can then read the counter at any time to determine how far they have traveled. This method is more exact than pacing if a reasonably straight line can be maintained.
