Both magnetic and electronic compasses do the same job. The digital compass may be easier to read for some people, can be integrated with track plotters and chart plotters and other navigation equipment. It is comfortable for I-Pod minded folk. The digital compasses often have additional functions like wind shift info built in. The electronic compasses can be stand alone or be integrated with other equipment down the road.They are accurate and reliable. But they do need electrical power.
A magnetic compass works with out electrical power but can be messed up by other electronics and wiring. You have to integrate its information to other navigation equipment yourself. They are accurate and reliable.
Both types of compasses do the same job. The cost range of both are also about the same. I like the digital Hi tech. stuff, but my wife ( The one who has sailed around the world. ) likes the magnetic type. We have both. Hers backs up mine when the battery is flat. 8-) She also likes a track plotter, I like a chart plotter....must be a gender thing.
