fluid in compass - SailNet Community Danforth (AquaMeter) uses Exxon Isopar-M as the oil and Ritchie uses Isopar-L, a lower viscosity oil (older models with no label on the bottom use odorless mineral spirits) You can’t use them interchangeable You can use Ritchie fluid in a Danforth but not the other way around Some compasses still use a water-alcohol mix using about 45% Ethyl

Refilling antique Sestrel Dead Beat compass with fluid It had a huge air bubble in it so I took it upon myself to take it apart to find the "refilling screw" that I had seen on other old compasses on youtube However, I enden up taking the plastic dome off and spilling out all of the fluid in there (over the sink, luckily!)
