Didn't know the super beast had some digital displays. Mine has analog and one of them don't work. The mega beast I have is brand spankin new. Little bulky but nice. Just got in a time domain reflectometer (radar) for finding high resistance connections.
The adapter for the superbeast is a must to check the return on the neutral.
Really though one can do a lot with a simple hair dryer plugging 5 amps.
