Davis Mark 25 Sextant



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 Davis Mk 25 Sextant, is a very accurate, precision piece of kit, the best Davis sextant available.

It has an 'all-view' (Full-field Beam Converger) with quartz hard coat which replaces the conventional half-silvered mirror. Horizon and astrobody images are combined in a single full-field for easy, reliable sights under the most difficult conditions.

It features a traditional half-silvered horizon mirror sighting and a beam converger with a full viewing field.  The special mineral coating is selective for different wavelengths of light which greatly increases accuracy. The 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. The LED will last for the lifetime* of the sextant. Batteries, which are included, will last up to 10 times longer than with regular bulbs. Positive push-on switching action, with vinyl boot water protection.
