Furuno has released its DS85 Doppler Speed Log, which is designed to provide the most accurate speed measurement possible and cover regulatory requirements for larger vessels as the next generation single axis speedometer. Beyond nature’s variance of extreme chop and heavy seas, boats create their own noise that can throw off sounding devices.

Furuno has devoted its extensive expertise to a new transducer design and coupled it with a higher operating frequency to cut through the noise. The DS85 also has more advanced processing algorithms to further clarify the signal.

“Vessel speed fore-aft is a significant factor in arriving in port, especially constricted navigation ways, and of course is supremely important when coming alongside the pier. The vessel master and mates need to know the speed of the vessel fore and aft to plan for all maneuvering,” said Matt Wood, Furuno’s national sales manager.
