The Davis Master Sextant Deluxe - Mark 25
Full-field Beam Converger with quartz hardcoat replaces conventional halfsilvered mirror. Horizon and astrobody images are combined in a single fullfield for easy, reliable sights under the most difficult conditions.

Mark 25 Sextant Features

  • Special mineral coating is selective for different wavelengths of light. Horizon is transmitted in one colour region and the star or sun in another.
  • Improved reinforced plastic stiffens frame for greater measurement accuracy.
  • High-efficiency LED (solid-state Light Emitting Diode) illumination system, which floods arc and drum with soft light. Positive “push-on” switching action, with vinyl boot water protection.

*Average LED half-life is approximately 10 years if operated continuously.
