Inclinometers

An inclinometer (also called clinometer, tilt indicator, gradient meter, and level gauge amongst others) is used to measure angles of a slope (usually of an incline or the ground's elevation). This is handy when plotting a hiking trip when driving a truck in mountainous areas, and, of course, when doing construction surveys. 

As time goes on we are seeing more and more technology in all-in-one devices. Most total stations (robotic or otherwise) can do both jobs. However, when you're just running over some details and want to quickly check your numbers out, it's a whole lot easier to whip out a compact  inclinometer. Check out these handy devices. No tripod setup needed!
