Review on Santronics 3000 Ultimate Sensor 50 1000VAC by Antonio Baker

If you own a home you will do all kinds of electrical remodeling I think if you are not afraid of electricity like adding switches, lights, changing outlets, whatever. Of course, when you do all of this, turn off the switch that you think is powering the area you're going to be working on. Well, sometimes this is not the case. Yes, you turn off the switch for the specific light you're working on, but guess what? There are also wires connected to other switches that are not turned off, they are live! Then you need such a device to ensure that you are not working on a live or hot wire. I like the precision of this device, for example on duplex cables it tells you which side or cable is hot (LED is on) and which is neutral (LED is off) and the LED is very bright. The beep is quite slow, it beeps, but it takes a second or two after the LED lights up.
