These pocket sized compasses are a perfect accent to your hiking packs or paracord projects. They double as zipper pulls, key fobs, or an emergency compass. The small compass is liquid filled for extremely accurate readings. The clasp opens and closes so you can remove the included nylon rope and replace it with paracord or other cordage. The clasp can fit two ends of 550 cord making it a great piece to cap your paracord tips. Loop them on your bug-out bag, hiking pack, or use them to accent a paracord project. You can also hand them out to your group before a hiking expedition so nobody loses their way. These are magnetic compasses and therefore may not function properly if they are placed close to metallic objects such as: cell phones, metal watches, screws or nails inside wooden surfaces, other compasses, inside automobiles, and even high tension power lines can disrupt the magnetic reading. To get an accurate reading, be sure to clear the compass from all metal interference and take multiple readings to ensure your correct compass bearing.
