Davis Instruments Mark 25 Sextant

Davis Instruments is a renowned name in the maritime and meteorological industries, particularly famous for innovating affordable and professional-grade navigation tools. The Mark 25 Sextant is the flagship of their plastic sextant line, featuring an LED illumination system and a full-field beam converger. Unlike traditional metal sextants that are heavy and expensive, Davis developed these high-impact, weather-resistant plastic versions to provide sailors with a reliable, lightweight alternative for celestial navigation.

The company's journey began with specialized marine equipment and has since expanded into weather stations and vehicle monitoring systems. The Mark 25 represents the pinnacle of their nautical engineering, combining high-precision optics with durable materials suitable for the harsh marine environment. Today, Davis Instruments is part of the Advanced Environmental Monitoring (AEM) network, a modern conglomerate focusing on weather and environmental technology providers.
