The classic opaque background allows easy identification of WAC and Sectional chart scales.
The laminated design protects visibility of printed scales for years to come.
The dual scales are calibrated in statute and nautical miles. Size: 12-1/4 x 4 in - 33.5 x 10 cm. When the centre hole is placed over a meridian line and the top edge of the scale is aligned with the proposed track the heading to steer (zero wind) can be read from the fixed protractor. Distance is read from the 1:500,000 or 1:1,000,000 scales.

expected it lasted longer
My first plotter ever. Not the best one around as it simply broke in half after less then 2 years of use.
