Depth Sounder as a Navigational Aid
Posted 2016, Apr 06 20:41
It was Jan Follstad during a US Power Squadron course in 2008 that pointed out to me the obvious that a depth sounder can be used as a navigational aid. In 2012 Capt. Jeff Scroup, F/V Escapade, that told me that "in the days before GPS" he would follow the contour lines of the chart off the Pacific Coast when visibility was restricted. There are other uses for the depth sounder even in this day and age of GPS. Any suggestions ?
