For those of you interested in survey instruments, the latest (#70)
Canadian Caver has an article about a kit for modifying a Disto A3 so
that it records distance, azimuth, and slope all at once, substituting
for all the traditional cave surveying instruments. The CC author used
the thing in Lech and thinks it is at least as accurate as traditional
surveys. One big advantage is that you aim the thing at the station no
matter how steep the angle of the shot--none of that pretending you're
aiming in the right direction you do with a Suunto compass. See www.paperless.bheeb.ch
