• In the full-featured Mark 25 sextant, the conventional half-silvered mirror has been replaced with a full field Beam Converger™ mirror, sometimes referred to as a “full-horizon mirror”, which combines horizon and astrobody images in a single field for easy, reliable sights. 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
• Special mineral coating is selective for different wavelengths of light - horizon is transmitted in one color and the star or sun in another
• Precision machined slow travel worm gear
• Readings to within 12 seconds of arc
• Seven sunshades
• Light weight and corrosion proof, the Mark 25 is made of an upgraded plastic that is very stable
• Arc and drum are illuminated by a long-life LED
• Comes with instruction booklet and padded, shock-resistant carrying case
