Aquameter Gemini Binnacle and Flush Mount Compass Parts

The Gemini compass (4-1/2" clear dome)was manufactured by Aquameter for many years until the Aquameter Compass Company was taken over by Rule Industries. The Gemini was marketed by Rule Industries for a short period of time, until it was modified and became part of the Constellation line of compasses. Most of the important parts are still available. The Gemini compass uses about 24 ounces of compass fluid to fill it. Click on the parts diagram to enlarge the image. Parts with prices are listed below by the key number in the diagram.
