SpecializedTechnical / Nautical / Aviation
Quick answer
What does “wet compass” mean?
A magnetic compass where the magnetized needle or card is mounted within a sealed chamber filled with liquid (typically oil or alcohol), which dampens oscillation and allows for quicker, more stable readings, especially on moving platforms like ships or aircraft.

Meaning and Definition
A magnetic compass where the magnetized needle or card is mounted within a sealed chamber filled with liquid (typically oil or alcohol), which dampens oscillation and allows for quicker, more stable readings, especially on moving platforms like ships or aircraft.
In modern usage, the term is often synonymous with 'liquid compass' and can refer to any precision magnetic compass designed for navigation where the damping fluid is a critical component. It contrasts with 'dry compass' designs.

FAQ
Frequently Asked Questions
All 'wet compasses' are magnetic compasses, but not all magnetic compasses are 'wet'. 'Wet compass' specifies the liquid-damped construction, which is common for marine and aviation use.
The term is purely descriptive of its internal construction—the magnetized element is immersed ('wet') in a damping fluid within a sealed chamber.
Yes, if the seal is compromised, the damping fluid can leak out, which will impair the compass's damping function, causing the needle or card to oscillate excessively and become difficult to read.
Typically a clear, non-freezing, low-viscosity fluid like a type of oil (e.g., mineral oil) or an alcohol-water mixture. This provides damping without overly restricting movement.
