Yes, they do, although in a few areas ferruginous igneous rocks or magnetic iron-ore close to the cave can introduce errors.
Until the recent invention of range-finding and position-locating instruments like the "Disto" (t.m.) the three measurement instruments for surveying caves were a builder's tape-measure for distances, a clinometer for slope angles and a magnetic compass for bearings. The latter two are types calibrated and read to 0.5º.
In high-grade cave-surveying the lengths and angle measurements from the above were, or are, then usually converted to (x,y,z) co-ordinates for plotting.

What do you call a person who fixes compasses?
A person who fixes compasses is typically known as a compass adjuster or compass technician.
Do astronaut need compass?
Sure, astronauts use compasses frequently, but on the Earth ground, not in space. Compasses only work in two dimensions on a surface like Earth's, where there is a significant body of iron in the celestial body's core. Then only if the core is magnetiized, which it would most likely be, due to the spin of the celestial body. Astronauts in space are in 3 dimensions, and in space there is no iron core to be magnetized. Compasses are useless in space, assuming they are far enough away from Earth to not pick up Earth's magnetic flux lines.
Would a magnetic compass be suitable to be used for space travel?
No. Magnetic compasses work based on the Earth's mantic field, in space there is no magnetic field for the compasses to work with. A different system, possibly similar to Global Positioning System (GPS) might work, call it the Universal Positioning System. On certain rocky planets it could work, but some planets don't have a magnetic field, like Mars. So a traditional magnetic compass wouldn't work in space, or at least it won't get you where you want to go.
Did explors use compasses to find their way or did they have other stragies?
Explorers used compasses as a primary tool for navigation, especially at sea where landmarks were not always visible. In addition to compasses, explorers also used celestial navigation, maps, and landmarks to find their way. Each method had its strengths and limitations, and explorers often combined multiple strategies to ensure accurate navigation.
Where can you see stalactites and stalagmites?
Stalactites and stalagmites can be seen in caves, where they form over thousands of years due to mineral deposits from dripping water. Popular caves where you can see these formations include Carlsbad Caverns in the USA, Waitomo Caves in New Zealand, and the Cango Caves in South Africa.
What is a sentence using compasses?
None of their compasses would work because of the magnetic ore in the hills.
What is the possessive form of the word Compasses?
The plural possessive for compasses is compasses'.
Where did the miners work?
caves
How magnets work in everyday things?
they work in eg. compasses, fridge doors, and in some handbag clips.
How many types of compasses are there?
There are two main types: Magnetic compasses and gyro compasses.
How do compasses work with the magnetic field?
Compasses have a magnetic needle that aligns with the Earth's magnetic field, which points to the magnetic north pole. This allows the compass to determine the direction of north and other cardinal directions. Magnetic compasses are based on the principle of magnetism and are essential for navigation.
What is the possessive form of compasses?
The possessive form of compass is compass's.
How do nautical compasses work?
Nautical compasses work based on the Earth's magnetic field. The compass needle aligns itself with the magnetic field lines, indicating the north-south direction. The compass rose on the compass card provides reference points for navigation.
What is the plural form of compasses?
Compasses is the plural form of compass.
What are the different types of compasses available for navigation and outdoor activities?
There are three main types of compasses used for navigation and outdoor activities: magnetic compasses, digital compasses, and lensatic compasses. Magnetic compasses use a magnetized needle to point towards the Earth's magnetic north. Digital compasses use sensors to determine direction and often have additional features like GPS. Lensatic compasses are more advanced and have a sighting lens for more accurate readings.
What is the plural of compass?
The plural of compass is compasses.
Can compasses harm the environment?
Yes compasses can harm the environment if you lave it on the sheet .
