Have to agree about GPS in the boat for sure, saved me a couple times out on G Bay, one minute it's sunny, the next your in a fog bank you can't see 20 feet. About 15 years ago, out salmon fishing very early, still dark. As the sun rose, the fog rolled in and then it was GPS navigating only, other than checking the depth on the F/F. Remembered to "believe" what the GPS is showing you, took me directly back to the dock that I couldn't see until the last 20 feet. A few others out there were hooting and hollering, rather funny but not. One guy ended up around on the claybanks about 3 miles from camp.
