We used to make these in the Army. For the price, just buy it and save some time. You have ten beads below and four on the top. You use the bottom ones first. For every 100 meters that you go, you slide a lower bead up to the knot. After ten beads, that is one kilometer, then you slide a top bead up and slide the bottom ones down again, keep on going up to four kilometers. If you are moving more than four clicks (kilometers), add beads to the top. One hundred meters is 333 feet roughly. Go out and find some varying terrain off the side of the road. Measure out 333 feet using a 100 foot tape measure. As you go along, have another person roll out and tie to every few trees a tape that is used as a "hand rail" for people using the pace count course. Count every time your left foot hits the ground from beginning to end. Then you know your pace count, and when to slide a bottom bead up. I am 5"6", and my pace count is 66. I did this kind of stuff for 22 years in the Green Berets. You can also set up a pace count course by measuring with a vehicle. Every tenth of a mile on the odometer is 160 meters, therefore, there you have one mile equaling 1600 meters. Not hard to do. Always know the basics of land navigation, i.e., map and compass, pace count, because I have been out in the middle of nowhere and GPS batteries do die, and you can only carry so many batteries. Remember, everything you put in your ruck sack weighs you down. Learn the basics, then learn GPS. Airborne!, De Oppresso Liber. MSG (R), US ARMY SPECIAL FORCES.
