Calibrating an tribrach mounted optical survey plummet

[@steboulrase]

This is brilliant your way

How do you mark the point if you can’t look and mark at the same time…

[@202nixon]

Get a red and white (or make one) and just keep moving it till its right. It's a good workout for the hammies

[@202nixon]

Or get the missus to help

[@puckerfist6621]

I feel like this isn't the most accurate way to do this, probably more accurate to backsite check then spin the tribrack 180 at this point.

Can you explain a bit more? How would you actually adjust it to be correct?
