Thanks everyone! I think the above post from TAN might be the most important part. Could it be possible that since my transducer is only about 6 inches underwater that the top 6 inches is actually COOLER than what's a foot down? I know, dumb question but hey, look at who's asking The only thing that's REALLY messing me up is my Dad is getting the same kind of water temps that I am, and he's got a "big boys boat".
I guess I'm gonna assume that mine is 10 degrees off and try to figure out a way to check it. I have other temperature gages I can use but no idea how accurate they are. I'll work on it, but thanks everyone for heading me in the right direction. Stupid depthfinders...

P.S. - It's not me Eric, my temp goes UP when I can't catch any fish!
