I have to stake a property line that is obscured by shrubs and fences. Access to the lines will require setting the instrument in multiple locations on a flat tar roof of a low parking garage.
In the past I have used short pieces of lath to keep the tips of the tripod from digging into a soft roof. I was thinking flat paving blocks, or sandbags might be better. Wind should not be an issue.
Any suggestions on a better way to stabilize the setup, without poking a hole in the roof?
Thanks

THey use to make a device that had three (plastic?) blocks attach by small chains to a central point (to keep the blocks from spreading). The plastic blocks had a divot in the center for the tripod leg points.
I used to use a quarter or half dollar under each tripod foot.
Occasionally, I'd position three 9 inch wedges, and I've seen guys invert their plastic caps for rebars and put the leg points in those.
The local supply place has one of those tripod stabilizers Perry mentioned under the tripod set up in their office, and the LoInk catalog has one for about $35.
I have (3) of the following item: CST Floor Guide
I used them exclusively on a recent job where I had to set up on concrete floors, and they worked great.

This has worked for me
All are good suggestions, but I've had problems with the stability of that type of roof itself...trying to get the gun leveled up!
You can get washers in a variety of sizes at a hardware store to fit different situations.
It is possible to leave them in place if you plan to occupy the setup in the future.

Actually, I have one of these things Perry is talking about. Loink sells them. I only tinkered with it at the house and never in the field. It was quite a pain to get setup just right.
