Full-field Beam Converger with quartz hard-coat replaces conventional half-silvered mirror. Horizon and astrobody images are combined in a single full field for easy, reliable sights under the most difficult conditions.
● 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.
