I have both the black accurite and a zoo med temp gun. The accurite is reading (only been there for 10 min) 10 degrees hotter than my point and click. Both have new batteries. Does anyone us an accurite that had a really good temp gun? Are both my thermometers defective? Or maybe they really shouldn't be sitting in there for 45 minutes like everyone repeats? And it's still rising while he is sitting happily close to the same spot. I don't know what to think anymore.
