fairly popular with Ste Genevieve county surveyors in Missouri anyway ;) there is absolutely no sense in burning up man power hand holding a light on station that wont be in the same spot from the other side, but whatever. ;) we tend to use green. when red gets dim its very hard to see, but the flourescent green ones are still visible.

For what it's worth, I'm also a huge fan of green LED station marker lights. I have a bunch of them.

I concur with Barb - listen to Stan and do what he says!

(and, in the spirit of his full disclosure - I've done a few shots where we simply estimated the azimuths, having left the instruments on the wrong side of a very, very hard squeeze. The passage was dead-ended in any case; if the dig at the end had eventually opened up, we promised to come back and re-survey it. Never did, unfortunately.)
