4-1/2" Constellation , Flat Card (Closeout)

The 4-1/2" Constellation compasses are used worldwide for larger pleasure boats, ocean racing powerboats and sailboats, commercial vessels, fishing fleets and by the U.S. Navy and Coast Guard.

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. Dual reading cards are also available on 4-1/2" (114mm)models.

Production of these compasses was discontinued in 2010. We still have a limited quantity of leftover stock that we are selling at closeout prices.
