This Digital Angle Gauge is the newest tool you need in your tool kit. More compact, more precise and more versatile than a bubble level. It can replace your torpedo level for most applications. More importantly, it gives you crucial information about the slope of a surface. This is critical for installing showers that slope towards a drain, a patio that drains away from the house, a ramp that's wheelchair accessible, a stairway or driveway at the perfect elevation. Use it on flooring projects to ensure the installation meets the manufacturer's specifications, use it to fine tune and calibrate your mitre saw or your photo frames. It has a V-groove on all sides and a magnetic base, making it perfect for installing conduit or pipe. It provides an audible beep when achieving perfect level, so you can use it even when you have your hands full or working above your head. The display rotates based on which direction you are holding the device, so you can always get a good reading.
