The barometer on my 60cs came in handy this past week. The pressure dropped like a rock and after a few minutes had passed it went back up quickly. At that point, I new that hurricane Charley had passed by. Unfortunately, I can't do a screen capture because I can only get back 48 hours, and I needed the gps to get around blocked roads. However my 60CS reports my minimum elevation as -178 feet. The unit has not been below 110 feet above msl. During the storm I stopped watching the gps when the ambient pressure dropped below 960mb. I wish I could have taken a screen capture of the graph with xImage but I did not have xImage on my laptop and there was no power for the desktop.
