Pace counters, or ranger beads, are manual counting tools used to keep track of distance traveled through a pace count. Made of 13 or more beads on a length of cord that are divided into two sections, separated by a knot. 9 beads are used in the lower section, and 4 or more beads are used in the upper section. This system was originally developed by our military.
There are two ways to use the beads. One represents the paces you have walked, while the other is the distance walked.

 
Getting your pace count:

 
Measure out 100 meters
Walk the entire 100 meters while counting every time your left foot touches the ground
Use your typical stride and pace or your later count will be off

 
Using the Beads:

 
Each of the bottom beads equals 100 meters traveled
Each of the top beads represents a kilometer traveled
While using your pace count, every time you have traveled 100 meters, slide one bead from the bottom section down
Once you have used all 9 beads from the bottom section, you will then slide one of the top 4 down after you have traveled another 100 meters. This means you have traveled 1 kilometer.

 
Meters, Kilometers and Feet

100 meters = 328.08 feet

1000 meters = 1 kilometer

Ranger Pace Counting Beads are a simple way to measure distances traveled by foot, particularly at night when visibility can be an issue. They are also very easy and inexpensive to make. Cordage with two sets of beads! For a more detailed tutorial check out http://www.instructables.com/id/Army-Ranger-Beads…
