Mains test screwdriver: proximity test

[mike004]

A visiting electrician had a mains test screwdriver that you just hold near to the cable, to show whether it is live.
I can't find these on the web. How much do they cost?

Google 'voltage detector' but don't rely on them for safety, i.e. testing for no voltage.

Thanks.
Voltage detector pens, they are called.

I thought it was a screwdriver as well.

Some are but don't buy one of them.

You have to touch the live wire with them.

This is a screwdriver with a built in non-contact voltage detector:
