No circuit tester and meter? Couldn't be without them.
I've got a Square D tester (old, but still works a treat) and a rather cheap multimeter - been promising myself a Fluke for far too long now.
Talking of Fluke. I was rather amused the other day, whilst watching the last episode (series one) of the new Battlestar Galactica, to find the marooned personnel using a "sensory device" that appeared to be little more than a Fluke Scopemeter . . .
I'm not entirely sure which model was used, but they do at least look the part, which is something that could not be said of the hair drier once use in Space 1999.
