All Ritchie compasses are built with ultra lightweight dial assemblies. Therefore, we don't need to use heavy fluid to artificially dampen the movement. Our compasses are filled with a highly refined, very low-viscosity dampening fluid which allows the dial to move smoothly within the bowl and lock on to magnetic north faster than other compasses. Ritchie's Dampening Fluid is also refined for brilliant, optical clarity.
