MADE TO ORDER - PLEASE CONTACT US FOR CUSTOMIZATION
Our uniquely designed ring was designed to aid you in keeping track of the distance you have traveled during hikes, land navigation, or runs. This ring is also perfect to use to keep track of laps, workout sets, or basically anything in your life that you need to count. For land navigation purposes, every time you walk 100 meters, just turn the ring one click forward to accurately keep your distance traveled. This ring improves upon the concept of the Army Ranger beads used during land navigation.
When selecting a ring size, we suggest selecting the size that fits your pointer finger.
Calculated Survival designs, manufactures, and sells our own innovations and ideas. For more information on land navigation and how to use our ring, please see our YouTube land navigation videos which teach you how to plot points on a map and how to be able to walk to them by using a compass and your pace count.
