Eliminates resetting the True Course to read the Magnetic Course.
APR’s New DAP-1 Rotating Azimuth Plotter is the only top scale plotter that has East & West Variation Scales where the True Course is read. The Magnetic Course is read directly opposite the Magnetic Variation Scale.
This eliminates the need to remember to correct for variation or to resert the rotary azimuth to a 2nd scale to read magnetic course. Compare this plotter to other plotters and see the differances and advantages of APR's superior Plotter.
