Fluke T+PRO Electrical Tester,Small

This is hands down the best tester you can buy. Mainly because it gives an audible and visual indication of voltage. I was tired of Klein testers that you have to look at to know if there is voltage or not. Often as an electrician it is hard to put the probes where you need them and look at the tester. The Pro+ is better because it gives you a digital readout of your voltage instead of just the lights.
