One post away from being able to post the PDF, I think you should make it happen.

Looks like more than a typical manhole, for typical manholes I like the idea of using a "hidden point" rod.

The gray retro-reflective stripes attract edm camera less than the yellow plastic style. Running a 6.5 rod helps as well.

I think you will have to go Beverly Hillbillies and strap some pipes to the roof for tripods and rods, maybe there is a step attachment for the tail h...

I do not fault a fellow for measuring with a hose, the one that gets my goat is the owner who was informed where their property lines are and/or the p...

Save your money someplace else, quality tribrachs and tripods earn their worth. The old Wild ones and the old Sokisha ones are good if you need to sav...
