Hi Sevver! Great idea to test the transit, I would never have thought to do it, thanks. I'm pretty unfamiliar with this thing, but I think I understand your instructions : set up two blocks or posts that I know to be level, put the transit in-between so that I have to turn it 180 degrees to get the same number for both, then move the transit so that it is in line with both blocks in front of it and test to get the same number.....

I know I'm turning this little pool "installation" into a much bigger deal than it needs to be, but I am thoroughly enjoying the learning process. I'm a dork.
