Step 5: Using Ranger Beads
First, find your pace count. For most people it's between 60 and 70 left steps for 100 meters. You can find out what yours is by measuring off the distance, then walk normally and count every time your left foot hits the ground (or right foot. It doesn't matter, just use the same foot each time).
Now, every time you walk that many steps, pull down one of the lower beads. Each one stands for 100 meters you've walked.
When you've pulled all of those down, pull down one of the top ones AND push all the lower ones back up. This represents 1000 meters.
Repeat the process for however far you're going.
There you have it. Trust me, it'll make your life easier in the field, especially if you're sorta absent-minded like myself. Hope this was helpful!
