You know, I've never had a no-contact tester, but I see most electricians using them now. So I will get one. They are not expensive and nice that you don't need to mess around with those goofy prong things.
The one I've always used is a simple one like this that has lights on it:
That joke I made about architects probably pertains more to landscapers, I guess...lol....
Other than volts the only thing we sometimes deal with is resistance in checking solenoids.
I have special device for doing that. And I also have a locator for tracing underground wires in order to find remote valves that have gotten buried over the years. And another device that makes the solenoid chatter so you can hear it - which is pretty cool.
I also have a nice meter I use for my low voltage landscape lighting.
Those things aren't used very much but when you need one they are super handy.
