Crossing from Mount Desert Island to Little Cranberry Island in the fog, my GPS failed, and I used my chart (in a waterproof case) and my deck mounted compass to make the crossing. I had to alter course to deliberately hit the northern end of Sutton Island. I'm glad I planned on the backup.
Bushwhacking in the Sandwich Range in New Hampshire, another time, my GPS failed. Again, map and compass to the rescue.
It wasn't an issue of the conditions of the moment, but rather what I suspect was the build-up of crud on the receiver over time that led to a failure. After two failures, I threw in the towel on the devices. Maybe I was too hasty, and I'm not suggesting people toss them, but for me, I simply cannot put my faith in them anymore.
