Sextant Davis MARK 25 / Alat mengukur sudut horizon / Alat navigasi

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.
The Mark 25 is illuminated by a long-life LED and made of an upgraded plastic that is very stable.
Comes with instruction booklet.
