Measuring modes and display units can be changed at any time. All
functions are controlled with two buttons. The 45158 displays maxi-
mum, average, and current wind speed in knots, meters per minute,
and Beaufort scales. Quickly select temperature measurement in °F or
°C. The compact, rugged weather meter is water resistant, and the unit
also features automatic shut-off. Similar to the standard wind meter,
the 45158 also offers data hold, detailed instruction manual, protective
plastic housing, tripod-mounting connection, and a water resistant hous-
