Silva Expedition 4 Compass
The Expedition 4 has a large baseplate to improve handling on maps and charts in the field. A full-sized baseplate not only makes it easier to hold you compass steady on a map, it's also easier to plot a bearing and take measurements.
The magnifier aids attention to fine detail and there are Romer scales at 1:63.360 1:50.000 1:25.000.
