This 2-scale instrument features a toggle switch on the bottom of the case, which allows you to view winds on either a 0 to 40mph (0 to 64.37km/h) or 0 to 120mph (0 to 193.12km/h) scale. The Gust Register is for the 0 to 120mph (0 to 193.12km/h) scale.
This instrument displays wind speed data as a number on its red, multi-digit LED display and wind direction displays via red LED dots arranged in a compass rose pattern along the outer edge of the face of the instrument.
