has anyone done a test of the effectiveness of a rod put in this way
compared to a hammered in rod? it would seem to me that using the
'water drill' is creating a larger hole. this is evidenced by the
comments that the rods are also easy to remove. but doesn't this
reduce the surface contact area with the earth and therefor increase the
resistance of the ground? i would expect a hammered in rod to have
better contact with the surrounding earth and probably provide a lower
resistance contact to it.

Here among the Big Bolt contest group, we've found that a quarter of a stick
is about all you need. Backfilling might take some time, but this also works
wonders for tower bases and guy anchors. A really delightful spinoff is the
effect it has on the neighbors: never a complaint again.
Remember to practice safety at all times. Count your fingers before and
after installation.
