Analog barometers are the simplest kind and are remarkably accurate. Most can be adjusted for your elevation and have two hands—one showing the pressure and another set earlier that will indicate whether pressure is rising or falling. Not too many years ago, analog was the only type of barometer available, but even with newer technology, analog barometers still hold their share of the marketplace. Unless you can hang them near enough to a door or window that you can read the face from there, however, you'll have to go outside to check the pressure. For some who prefer to stay indoors where it's warm in the winter and cool in the summer, that can be a deal breaker.
