Precision tool that can measure the angle and length accurately and quickly with a digital readout of the angles. Measure both the angle and length at the same time with a clear display and bold markings in both metric and imperial on the rules. The rules are made from corrosion resistant stainless steel. The battery life is around 200 hours and is protected by auto shut down after 6 minutes. The digital display will auto-start, switch on as soon as you open the rule, saving time and fumbling for a button. A serious tool for any wood working, building, machining and construction industries or setting out tasks.
