It was I-4 outside of Tampa Friday. I was around a "mild" curve and down a slight hill on the highway. I got a 1.2 mile range. Not bad, I bought the detector in Jan 2001. :shock: I live in FLorida and NEVER take the detector off of the dash. The temp in my car in the summer hits 140F, too. I hope the detector keeps tickin' along until the nest big thing comes along.
