Vertical compass

[deacon]

I've seen and read somewhere about a compass that is carried at your side verticaly(instead of held horizontally) and used to detect mineral deposits. Are these a special type of compass? as I don't see how my liquid filled hiking compass would work. Is the compass used as a pendulm?
Any info appreciated.

What you probably have reference to is a Spanish Dip Needle.

Here is info on how they work...
