The Adlard Coles Book of Electronic Navigation imr_RB0004

Description: he Adlard Coles Book of Navigation is aimed at anyone with an interest in navigating small craft,but particularly at those working towards RYA Day Skipper, Yachtmaster, Motor Cruising or Advanced Powerboatcertificates, or attending the RYA Radar course.Electronics have gained such widespread acceptance over the last decade that even a modest family cruiser is likely to have anelectronic navigation capability comparable with that of a small warship of twenty years ago. Using plain English to strip away thejargon, this book sets out to demystify the technology behind modern marine electronics, and to explain how the various systemswork and how to get the best out of the equipment available..
