A very handy digital protractor, ideal for steel work due to its strong alloy body and built in base magnets. With simple calibration and a display that always reads the right way up, it's easy to use and read. It has a hold facility so that you can use it where you cannot read the display. A "V" groove in each side makes it suitable for use on tubular work, so it would be great for setting up guard rails on stairs etc. A very useful device supplied with a battery.
