Hey Pete,
That is the way Jim surveyed, though, and I surveyed with him. Also
back-sighting same way etc. He was a stickler for good closures, and when I met
him I was working as a draftsman and mathematician for a surveying company. I
would draw up land surveys from field notes with a
Hi Mimi!
The Brunton is more accurate if you tripod-mount it and use the shadow method.
But then you need to add instrument height and light height. People are often
too lazy to do that, however.

I’m with you Pete. Jim never went to Suunto - always Brunton. But then he did
not do much wet cave surveying, nor deep vertical stuff. Although he will never
go caving again, we still have lots of carbide lamps and some carbide, along

Brunton’s also work well, but there is hardly anyone left that knows how to use

George, thanks for sharing this. Ben Meadows and FS used to be competitors.
I'm glad at least one is still going. I just tossed my old hardcopy catalogs
from them the other day. Around 2006 we started noticing that the face of
Suuntos was getting cracked frequently. They had changed to some
While many cavers are now using DistoX2s for surveying, many of us still have
and use Suuntos. I was on trip yesterday and found the face of my Suunto
compass had cracked, creating a large bubble inside the instrument that makes
it hard to use accurately. Years ago, I'd send my Suuntos off to
