A necessary item for every home in California. This is a really good invention. Here in California, we have quakes all the time. But some are so small that we can't really feel them or just don't pay attention to them. But all of these little quakes matter as they determine a shift in the earth's plates which could lead up to the big one. Having this will give you an idea of what is going on underground.
