4-1/2" Constellation

Originally designed by Aquameter Compass Co. of New Jersey and marketed under the Aquameter Gemini name for many years this line was taken over by Rule Industries and incorporated into the Danforth Constellation Line.

The Constellation® compass features an internal gimbal ring that allows full tilt and heel, a virtually indestructible jewel and hardened alloy pivot and a unique concave distant reading card that lets you read it from longer distances and at lower angles of sight.

These were available in flush and Binnacle mounted styles, for power or sail, these prestigious compasses provide uncompromising quality and performance for the most discerning yachtsmen.

Theses compasses are completely repairable and Viking Instruments owns the tooling necessary to continue to supply replacement parts and service.
