G'day all,
I saw a machine recently which had a "live wire alarm system" installed in the cab. From what I can tell it detects the 50Hz electrical field around power lines using a small aerial mounted on top of the stick.
Has anyone had experience with these devices? Are they actually of any use or like many such things is it too late once it goes off?
Here's an example of it

On paper as far as I can tell I'm thinking it should be standard equipment in all excavators...
