10 minAim-Off Navigation: Guarantee Striking a Linear Target
Learn to intentionally deviate from a straight bearing to confidently intercept long, narrow features like trails or streams, preventing overshooting.
- Identify your current position and the linear target (e.g., trail, stream) on your map.
- Determine the magnetic bearing from your current position directly to your target.
- Select an intentional offset angle, typically 5 to 20 degrees, in one direction (e.g., clockwise or counter-clockwise) from your direct bearing.
- Calculate your new, offset magnetic bearing by adding or subtracting your chosen angle.
- Walk on your offset bearing until you intersect the linear target.
- Once you hit the linear feature, determine which way to turn to reach your objective.
Tip: When in doubt about which way to offset, choose the direction that leads you to a more identifiable part of the linear feature, such as a major intersection or a prominent curve.
Warning: Always factor in magnetic declination for accurate bearings.

10 minCompass Resection: Pinpoint Your Location Using Two Peaks
Use your compass and a topographic map to accurately determine your precise position in the field by taking back-bearings from two known geographic features.
- Identify two distinct, named geographic features visible from your position that are also clearly marked on your topographic map.
- Orient your map to true north using your compass's declination adjustment and magnetic north needle.
- Take a precise magnetic bearing with your compass from your current location to the first identified feature.
- Convert this magnetic bearing to a true bearing by applying magnetic declination in reverse (add declination for west, subtract for east).
- Plot the reciprocal (back-bearing) of this true bearing on your map, drawing a line from the identified feature back towards your location.
- Repeat steps three through five for the second identified feature.
- Note the intersection point of the two plotted lines; this is your approximate current position on the map.
Tip: When possible, use features that are roughly 90 degrees apart from your position; this geometric arrangement provides the most accurate intersection.
Warning: Always carry a backup method of navigation, and know how to use it.

10 minCalibrate Your Pace Count and Track Distance with Ranger Beads
Learn to accurately calibrate your 100-meter pace count across diverse terrain and use ranger beads to track distance, essential for navigation in challenging conditions.
- Identify a known, measurable 100-meter course in varied terrain, ideally marked or easily measured with a long tape.
- Walk the 100-meter course at your natural, sustained hiking pace, counting every time a specific foot (e.g., your left foot) touches the ground.
- Record your pace count for this 100-meter segment, then repeat the process several times to find an average pace count for that terrain type.
- Repeat the calibration for different terrain types you expect to encounter, such as uphill, downhill, dense brush, or open flat ground.
- Assemble your ranger beads: 9 lower beads representing 100-meter increments, and 4 upper beads representing 1000-meter (kilometer) increments.
- Begin navigating, sliding one lower bead down for every 100 meters you cover (one pace count), and slide one upper bead down each time all 9 lower beads are moved.
- Reset the beads by pushing them back to their original position once you reach your destination or complete a leg of your journey, noting the total distance.
Tip: To reduce mental load, make a habit of moving your bead immediately after completing your 100-meter pace count, possibly by associating it with a quick mental check of your surroundings.
Warning: Mistakes in calibration or counting can lead to significant navigational errors; practice diligently.

8 minAdjust Declination and Orient a Map in the Field
Learn to accurately set magnetic declination on your compass and orient a map to true north, crucial for precise navigation in the field.
- Locate the magnetic declination for your current area on your map's legend or a reliable online source.
- Adjust your compass's declination setting ring to match the value and direction (east or west) you found.
- Place the compass flat on your map, aligning its edge or baseplate with the map's true north/south grid lines.
- Slowly rotate the map and compass together until the compass needle aligns perfectly within the orienting arrow on the compass baseplate.
- Confirm the map's features now visually align with the physical terrain around you.
- Take a bearing from a known distant landmark on the map, then re-verify that the compass bearing matches the landmark's actual direction.
Tip: Some maps provide a diagram showing the relationship between true, magnetic, and grid north. Use this to double-check your declination setting.
Warning: Be mindful of local magnetic anomalies caused by metal ore deposits or power lines, which can cause compass errors.
