I wonder what difference there are between the residential ones compared to the aviation ones...that is how accurate they are and how well they respond to altitude changes. I didn't see any information about the residential ones about elevation deviation errors or auto-calibration.

Guess I'll have to work on that one and ask the funny questions to the manufacturer... <img src="/forums/images/graemlins/smile.gif" alt="" />
