Quick Reference Navigation Cards
Used by the US Coast Guard, US Coast Guard Auxiliary and US Power Squadron, Davis Instruments' navigation reference cards are engineered for fast, accurate information retrieval when you need it most. The Navigation Rules Quick Reference Card includes the US Buoyage System, Inland and International Rules, Right-of-Way, Lights, Sound Signals, and Bridge Signals, providing comprehensive coverage of essential maritime regulations in a compact format.
The Navigation Rules Card is full color on both sides, and it is three-hole punched for a binder or bulkhead mounting, making it easy to keep critical information accessible whether you're at the helm or studying below deck. All information is presented in graphic summary and easy to read formatting. Complete, precise, accurate, these cards eliminate the need to thumb through books during time-sensitive situations.
Celestial Navigation Work Forms and Guides
For navigators practicing traditional celestial navigation techniques, Davis offers specialized work forms and reference materials that simplify calculations and reduce errors. The Celestial Navigation reference includes everything you need: sextant use and corrections, starfinder for 18 stars, data entry form, and step-by-step sight reduction and plotting procedures. It may be scored and separated; large portion fits in the sextant case for quick reference, and small part acts as a waterproof data reduction card, demonstrating Davis's understanding of practical maritime needs.
Davis also produces HO-229 celestial navigation work forms, designed to streamline the calculation of celestial observations for principal navigational stars and Polaris, helping navigators work more efficiently and accurately.
