That tester does have other ranges, you really do need to learn to use it properly. It has various megohm ranges used in its IR testing function.
It is not the tester that can't do its job properly, it was designed for carrying out testing of new installations and periodic inspections and it does this perfectly well. It was not designed for fault finding work!
An analogue IR and continuity tester is the best thing for general fault finding in my opinion (and most electricians I know) with a multimeter also being useful on occasion.
