Davis Mark 25 Sextant Instrument for Navigation with Davis Artificial Horizon Bundle (2 Items)


Davis Mark 25 Sextant and Davis Artificial Horizon Bundle (2 Items)
The Mark 25 is a top of the line working sextant featuring our Beam Converger & Trade Mirror often referred to as a "Full Horizon Mirror". The Full Horizon Mirror was designed to make readings easier by filtering and simplifying the light coming in through the lenses.
The Artificial Horizon answers the need of every sextant user who cannot depend on a natural sea horizon, allowing you to be able to practice on land and at home. It comes with two sunshades, a lid, and full directions to help you get familiar with these instruments. Great for backyard practice! To use, fill with water and read the angle of the reflected sun with your sextant. Half your sextant reading is the sun & angle above the true horizon.
