There are two types of compasses, (a) liquid filled and (b) non-liquid filled. Liquid filled means the compass is filled with some special liquid so the magnetic needle floats freely inside of it. Non-liquid filled means there’s no liquid inside of it (duh?) but instead the magnetic needle is able to rotate freely while being balanced on one or two pins inside the compass. So which is better? They both have their pros and cons, the only difference is that the North seeking magnetic needles inside liquid filled compasses rotate & move slower than non-liquid filled compasses. But regardless of which type of general direction compass you have or get with your survival kit, they’re a lot more easier to use in determining directions than these techniques below “without a compass.”
