A sextant is an excellent tool to have on board any size craft as a backup in case there is a failure of the navigational systems. Used to measure the angular distance between two visible objects, th e most common sextant navigation points are an astronomical object and the horizon. Sextants have many uses, ranging from measuring the distance of a landmark to determining Greenwich Mean Time.

The top of the line Davis plastic sextant, the Mark 25 features our Beam Converger™ mirror, sometimes referred to as a “full horizon mirror”. A special coating is applied to high quality optical glass to allow the user to see through this mirror, yet still pick up images as faint as low-light stars.
