The annual campout is only two weeks away! I still have to work the next couple days but I will be out early next week scouting… I'll start by saying this though....
Yes, especially in the summer time the posted usgs temps are sometimes significantly different than my Hummingbird readings. Like 10 degrees different and during the summer the water temps don’t fluctuate like the do in the springI get what you are saying on depth finder, but if you understand where the temp gauge is, it can get a bit wonky at times. I’m probably going to try this afternoon & will take some temp measurements the old fashioned way.
