Davis #11 Mark 3 Sextant Bundle with #144 Artificial Horizon & #132 Celestial Navigation Quick Reference Chart (3 Items) Mark 3 Sextant - Sometimes referred to as a "lifeboat" sextant, the Mark 3 is an inexpensive training sextant.

Artificial Horizon: Answers the need of every sextant user who cannot depend on a natural sea horizon.

Half your sextant reading is the sun & angle above the true horizon. Comes with two sun shades, a lid and full directions. Celestial Navigation Quick Reference System.
