Sextants are just as vital today as they have been in the past. Although GPS units are becoming the standard, they can still fail due to power loss, down satellites, dead batteries or flooding, leaving boaters and sailors without navigation instruments. A practical navigational backup tool, the Mark 15 and Deluxe Mark 25 Sextants from Davis Instruments deliver accurate readings to 2/10 degree.
Featuring a precision-machined, slow travel gear and worm mechanism, the dependable Mark 15 has a 7" frame radius graduated from 120 to -5 degrees. It also includes seven large sunshades, a star scope with anti-reflective glass lenses and a separate hooded sight tube for glare-free sun shots. Designed for the harsh marine environment, the durable sextant has a contoured handle and angled back for a steady grip and added control.
The Deluxe Mark 25 Sextant adds a Beam Converger, LED light and advanced mineral coating. Replacing the traditional, half-silvered mirror, the Beam Converger provides a single, full-field view for reliable sights, even under the most difficult conditions. The highly-efficient, long-life LED illuminates the arc and drum, while a special, mineral coating enables users to see the horizon in one color and a star or the sun in another. This helps to pick up faint objects such as low-light stars as well.
With a detailed instruction booklet and tough, fully-padded, shock-resistant carrying case, the Davis Mark 15 has a suggested retail price of $215.99 and the Deluxe Mark 25 is $299.99. A Mark 3 training sextant is also available for $59.99.
