Davis Mark 25 Deluxe Master Sextant

Deluxe Mark 25 Master Sextant with full-field dielectric Beam Converger

This top of the line plastic sextant features a full-field Beam Converger™ mirror, sometimes referred to as a "full horizon mirror". This replaces the conventional half-silvered mirror and means the horizon and astrobody images are combined in a single full-field for easy, reliable sights under the most difficult conditions.

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 frame is made of reinforced plastic which stiffens the unit for greater measurement accuracy.

The Mark 25 is illuminated by a High-efficiency LED, which floods the arc and drum with soft light. There is a positive "push-on" switching action, with vinyl boot water protection, and batteries are included.

Supplied with a foam-lined carrying case and instruction booklet.

2. We'll then give you a returns number. This returns number will need to be clearly marked on the outside of your parcel so it can be identified on arrival. Please note, failure to mark a returns reference number on the outside of your parcel may result in a delay in processing your return.
