If 135° is not abnormal, then we are all in for some serious weather situations! All kidding aside, I have been going through some interesting things with my transducer as well . It is not the same, it is electromagnetic, but it is also airmar. For a period of the summer I was getting readings like 140 150. Then they would change to somewhat more normal. I found that unplugging the n2k cable, and then plugging it back in again, sometimes helped. Eventually, about a month ago, the readings came to near normal around a three degree adjustment on my part. I have no idea what could make it do these crazy things.
