It's closing time and I'd like to spend the big money and fit a loop-loc ultra, only available here in Italy (AFAIK) from an Internet supply house, so I have to measure up and install myself.
The pool has no straight edges and is not symmetrical about either horizontal axis, it's 53 x 23 feet so a bit big (and wet, and cold...) for tape measures etc. I have a laser measure so I'm thinking that setting up a datum down the middle of the pool (stretched tape or rope) to act as a laser target, then measuring from the edge every 20 inches or so could be the way. My question is : how do the pros do it? It can't be a new problem, so if there are any architect/engineers/surveyors or pool pros out there that can help, I'd be very grateful.
