Gravimeter
A gravimeter is a specialized measuring tool used in geological exploration to detect variations in the Earth's gravitational pull. It helps survey teams find valuable underground resources like oil, minerals, or hidden cave systems by measuring tiny changes in gravity. Think of it like a very sensitive weighing scale that can detect what's beneath the surface. Companies use this information to decide where to drill for resources or assess ground stability for construction projects. You might also see it called a "gravity meter" or "gravitometer" in job descriptions.
