I'm thinking I ought to get one of those little testers. They tell you a lot with little effort.
They claim the test the tester does will not trip a 30 ma RCD, that was one of the reasons I got it, the other as you say is little effort required, the EZ150 is under half the price of the EZ2500 that I got but the earth loop impedance read out is less indicative so to speak.
The test I just done was at a wet time of the year and the ground is soaked at the moment, I will check it again during a dry spell, the first few weeks of Autumn is usually the best time down here for the water content of the ground to be low at depth.
