The Nassau M51 Wind Direction Gauge is used extensively in the marine industry, and at many small airports.
When combined with the M50 Wind Speed Gauge, it provides the most accurate "at a glance" instant wind data reading available.
The M51 incorporates a true 360° analog indicator, which is driven by a high precision, aviation quality syncro. The indicator is driven around the 360° Scale, which is graduated in degrees, and includes 8 points of the compass (N, NE, E, SE, S, SW, W, NW)..
M51 is supplied with the special split tail wind vane (A2739) which reduces side to side flutter, 100 feet of cable, and all mounting hardware.
For decades, Nassau was produced by Danforth Instruments, earning a reputation for accurate, trouble free operation. These professional grade instruments are field proven, and used extensively by the U.S. Navy, U.S. Coast Guard, FAA approved airports, and in many industrial and research applications. Outdoor Environments LLC has continued the Danforth tradition, manufacturing every Nassau Instrument to exacting standards, for continuous professional use.
