Radar was useful on the day this picture was taken, but vital two days later when we transited the same area in thick fog.
Radar is, at least to Phyllis and me, the most important piece of marine electronics on our boat. Yes, more important than GPS or a chart plotter—we know how to find our position without GPS and we can navigate on paper charts, but neither of us can see in the dark or have x-ray vision to penetrate fog.
We also find radar’s ability to accurately measure the distance to an object and gauge if it’s moving, and if so how fast and in what direction, invaluable—humans are really lousy at this.
So, before we move on, I need to make clear that these recommendations are for those of you with similar needs to ours: radar is mission critical.
(Also, if you have not read them already, you need to stop here and read this chapter and this one too.)
