If you do metalwork, woodworking or fit flooring or cabinets, then you need this 3 in 1 digital angle finder from TOUGH MASTER®. The TM-AF360 digital angle measurer has a sturdy aluminium body that is ribbed for added strength to protect its highly accurate digital components; the robust stainless steel measuring arm is 2mm thick for extra durability, and has a measuring range of 0-360°. Because this 3 in 1 digital angle finder tool comes supplied with its own powerful 3V lithium battery, you can get measuring right away. Our digital angle gauge is accurate to within 0.15°. The large, easy to read LCD display screen measures 2.5 x 0.6 inches and has a high resolution of up to 0.05°. A quadrant indicator on the left top of the screen clearly tells you the current position of the measuring arm. If you need to invert this digital angle finder, the digital reading gets automatically inverted, too, making it easier to read while working. Thanks to the dual metric / imperial scale (in centimeters and inches), our digital angle measurement ruler allows you to make quick, easy measurements and quick, easy conversions. Lock the electronic angle finder into any angle with its handy locking knob: This knob can also be used as a stop for quickly checking common angles like 45°, 180° or 225°. Use the zero button to determine angle changes from the initial measurement, which is useful when measuring relative angles.
