I disagree with this. In general, deeper is harder, but I believe you
can successfully fish nymphs below an indicator much deeper than a foot
or two.

Well sure, you can fish a little deeper than a foot or two, with
and indicator, if you work at it. There is a threshold level
of depth where indicators stop being useful--beyond which
you're better off fishing without the indicator at all.
I had to fish that way this past weekend. The water was
cold and a little off color, and the fish were podded up
in deep water. When I found them I caught 3-4 per hole,
down deep. I used a barbell crazy charlie as weight
with a stonefly nymph behind that. It worked like a charm.
An indicator rig would have produced ungats. They were far
too deep for that.

I'll guess ungats is the also the number of fish you've
caught on Fish Pimps over the years. Hopper indicators
don't work well in early April. But they do work.
If it's the visual thing you like, you can make
a hopper indicator with a hot lime or pink wing.
If it floats well, and there is a wet fly behind it,
then it's an indicator. If that indicator has a hook
in it, ungats is not the number of fish you will catch
on the indicator.
